Vaishnava-vamsa, Vaishnava-jati, and Vaishnava-Acharya-vamsa

(From "Sampradaya: Asat-Sampradayas" - click to read more from it.
You can also read the previous page: Pseudo-vaishnava-dharma and pure Vaishnava Dharma)
– Are the following terms right and prestigious for the Vaishnava religion: Vaishnava-vamsa (Vaishnava dynasty), Vaishnava-jati (Vaishnava caste), and Vaishnava-Acharya-vamsa (dynasty of the Vaishnava Acharya)?
– There cannot be a Vaishnava-vamsa. There is no guarantee that every descendant of a particular dynasty will become a Vaishnava.
We are seeing many rogues take birth in various Vaishnava families, and they are
acting like demons.
Whereas many great people have taken birth in the family of dog-eaters and yavanas, and have become Vaishnavas on the strength of pure devotional service.
Many non-Vaishnavas are found in the families of Vaishnava Acharyas. On the other hand, many Vaishnavas have taken birth in the family of gross nondevotees.
The prestige that is given to the caste Vaishnavas and descendants of Vaishnava Acharyas does not increase the glories of the Vaishnava religion; rather the audacity of non-Vaishnava-Dharma is increasing.

Natural Brotherhood (Bhaktivinoda Thakura):

"Gradually, when the offensive portions of the established religions are destroyed, there will be no more differences in the bhajana performed by the various Sampradayas nor any quarrel between them.
Then as brothers, the people of all castes and countries will spontaneously chant the Holy Names of the Supreme Lord together.
At that time, no one will hate anyone or consider others dogeaters; nor will anyone be overwhelmed by the pride of high birth.
The living entities will not forget the principle of natural brotherhood."
