From what I think I managed to get out of this, someone commented on something someone (you?) did, and now he's being a very silly person about it while also bashing on baby/diaperfurs?
I'm probably a cubfur myself, and I like baby- and cubfur-art for as long as it clean in all ways possible (no messy soiled diapers and stuff)
People should be allowed to do the things they do and be what they want to be for as long as noone is getting hurt.
But sadly there will always be those who can't help but bash down on whatever it is they think is wrong/stupid/gross/whatever.
I have no idea what else to say.
This seem to be a thing between you and another person, and to be completely honest, you don't seem to be handling it all too well yourself either judging from the comments you've made..
I have no idea exactly what have happened since it's hard to get a good view of both sides, tho, so I can't really say much else...
So well, good luck with that, and IMO it'd be best to just drop the whole thing and not make such a big fuss over it...
