I'm not sarcastic but may be illogical. I admit about what you've said about Veda, but it's not a text to be decoded so easily. From time to time sages come to explain those texts according to time and circumstances and in a limited way. It happens because not everybody can understand the Vedas perfectly in this material world.
True, but that does not mean we should despise them and force them to learn something which is not to their calibre. It will be detrimental for them.
True again, but in some way or the other they are praying to those ones who are dear to God only. For e.g., Shiva is very dear to Hari, Buddha is an incarnation to Hari and so on. I know that what you would expect from a Vaishnav is far much higher than than of a Christian and Shaivate. But that's the rule in the material world you can never get real followers of Hari at one go in this material world. It is a settled rule, confirmed by Hari himself.
Jesus did what he can, I can never blame him for that. Infact i respect Him for that. I know for the followers of Jesus, it's mighty long and winding road but it's like that.
As concerning me, I know that I'm not a Vaishnava. I'm always in search of one. That's why I would certainly not mind to see Yamraj one day after my death, but the only thing I'll ask Krishna is let me remember who I'm actually facing, one of His Dearest.
And for sure I never mix Vaishnava with Christianity. Vaishnavism is the Universal set and Christianity is an element of it.
