Those Vaishnavas are beyond any material limitation

Some scriptural evidences are given below to avoid committing vaiṣṇava-aparādha—

yadi mora putra haya, haya vā kiṅkara

`vaiṣṇavāparādhī’ muñi nā dekhoṅ gocara                  

(CB Madhya 19/1750)

“I cannot look at the face of a vaiṣṇava-aparādhī, even if he happens to be My son or servant.

jananīra lakṣye śikṣā-guru bhagavān

karāyena vaiṣṇavāparādha sāvadhāna 

(CB Madhya 22/54)

The Supreme Lord, the instructing spiritual master of all, cautioned everyone about vaiṣṇava-aparādha by using His mother as an example.

śūlapāṇi-sama yadi vaiṣṇavere ninde

tathāpiha nāśa pāya, —kahe śāstra-vṛnde                                  

(CB Madhya 22/55)

Even if someone on the level of Lord Śiva blasphemes a devotee, he will soon be destroyed. This is the verdict of all scriptures.

ihā nā māniyā ye sujana-nindā kare

janme janme se pāpiṣṭha daiva-doṣe mare                  

(CB Madhya 22/56)

Sinful people who ignore this fact and blaspheme devotees suffer the punishment of providence birth after birth.

caitanya-siṁhera ājñā kariyā laṅghana

nā bujhi’ vaiṣṇava ninde pāibe bandhana                                 

(CB Madhya 22/120)

Anyone who transgresses the order of the lion-like Lord Caitanya by blaspheming Vaiṣṇavas will suffer the bondage of material existence.

vaiṣṇavera nindā karibeka yāra gaṇa

tāra rakṣā-sāmarthya nāhika kona jana                                      

(CB Madhya 22/128)

A Vaiṣṇava is unable to protect any of his followers who engage in blasphemy of Vaiṣṇavas.

vaiṣṇava-nindaka-gaṇa yāhāra āśraya

āpanei eḍāite tāhāra saṁśaya

(CB Madhya 22/129)

The deliverance of even a person whose followers engage in blasphemy of Vaiṣṇavas is doubtful.

Bhagavān can never excuse them-- those who criticize or insult guru-Vaiṣṇava. Poor-Rich conception or educated–uneducated conception not at all applicable for guru-Vaiṣṇavas. Also, Vaiṣṇavas are never belonging to any particular caste or by social status they can never be identified. Even if this kind of basic conception is not there in me, then how I can become a world class preacher? Sama darśana (equal vision) is the most basic backing in the way of vaiṣṇava-darśana or vaikuntha-darśana. I myself never want to become a world class cheater, so I can never enjoy popularity, that I know, but as per Śrīla Bhakti Siddhānta Sarasvatī Gosvāmī Ṭhākura Prabhupāda to seek the satisfaction of public (or to collect public vote) or to seek the satisfaction of the Supreme Lord is not one and the same. The first one is non-bhakti mood, whereas the second one is called bhakti. Who can justify such unusual remarks by our most honorable Svami Mahārāja (please look at the section 2 of the following link: https://www.echoes-of-eternity.com/vaishnavas-are-beyond-material-limitation)?

Śrīman Mahāprabhu wanted to teach us how to give extreme honor to Śrī Guru-Vaiṣṇava and how to protect their divine dignity by giving topmost honor to Śrīla Namācārya Śrīla Haridas Ṭhākura (though externally he was from Muslim family) and by rejecting Vallabha Ācārya for his negative mood of expression towards the commentary on Śrīmad-Bhāgavatam written by Śrīla Śrīdhar Svamipad. From Śrī Caitanya-caritāmṛta we know the following siddhānta vichar of Śrīman Mahāprabhu The Supreme Lord—

kibā vipra, kibā nyāsī, śūdra kene naya

yei kṛṣṇa-tattva-vettā, sei ‘guru’ haya

(Cc. Madhya 8.128)

“Whether one is a brāhmaṇa, a sannyāsī or a śūdra, regardless of what he is, he can become a spiritual master if he knows the science of Kṛṣṇa.”

The great exalted Vaiṣṇava Śrīla Bhakti Daiyta Mādhava Gosvāmī Maharaj was the only shelter or support in your helpless life of dangerous sickness for whom you got back a new life. Then how it is possible for you to forget him so easily? Surely Śrīla Bhakti Vijñāna Bhāratī Gosvāmī Maharaj was not informed at all about all those dirty remarks or criticism past by Śrīla A.C. Bhaktivedanta Svami Maharaj about his Gurudeva and guru-varga, otherwise it would not have been possible for him to glorify Śrīla Svami Maharaj that way (big way) in his book named ‘My Beloved Masters’. If we are failure to unveil the mystery lying behind the screen, then anybody can express doubt about our most honorable Śrīla Vijñāna Bhāratī Gosvāmī Maharaj, that how it was possible for him to glorify Śrīla Svami Maharaj even after knowing all those bad remarks passed by Śrīla Svami Maharaj about his own Gurudeva and guru-varga. From Śrīmad-Bhāgavatam we can get the following example established by Ma Sati Devi during the time of criticism of Vaiṣṇava Raj Syambu (her husband) by Daksa Prajapati, ultimately she left her body by the help of Yoga agni, because of hearing vaiṣṇava ninda.

From the article ‘Śrīla Uddharan Ṭhākura’ written by Śrīla Bhakti Siddhānta Sarasvatī Gosvāmī Ṭhākura Prabhupāda we can have the Gauḍīya siddhānta vichar established by him (please look at the section 1 on th same link: https://www.echoes-of-eternity.com/vaishnavas-are-beyond-material-limitation).

Also, Śrīla Saccidananda Bhaktivinod Ṭhākura expressed his great concern about such kind of humiliation of Śrī Guru-Vaiṣṇavas by those ignorant people, so he wanted to establish daiva varṇāśrama dharma through Śrīla Prabhupāda before leaving this material world. Also Śrīla Prabhupāda wanted to leave his body when he heard some insulting remarks passed by one so called pāṇḍā at Śrī Rādhā Kunda Braja Dham about Śrīla Ragunath Das Gosvāmīpad. We have no right to say that Śrīla Vamsi das Babaji Maharaj belongs to a fisherman’s family, or Śrīla Gaura Kisore das Babaji belongs to a vaiśya family.
