To be fair some of them have been extremely sweet and kind, particularly
one brother who is the most christian person I've ever met. He's just
moved back into my congregation and he wanted to just call and say hello
and he really is a lovely, kind person.
When a Buddhist who lives in China is sweet and kind and a Muslim from Turkey treats his wife and children well, is he said to be acting "Christian"? It's funny how Christians and JW's in particular, on a certain level of consciousness, believe being good and kind is limited to Christians and is proof that they are the true religion.
I can't tell you how many times I left that place in tears at the coldness shown me. So why the sudden bombardment??
Jehovah's Witnesses are not a live and let live religion where people are encouraged to have a relationship with God in their own individual way. A lot of them want to see you doing what they are doing because it validates them. My guess is that this is because they are one misplaced thought away from straying themselves and it makes them nervous to see something or someone out of place. People who can barely control themselves figure everyone else is the same way and they project their insecurities onto others and try to control them in an effort to make themselves feel safer. It probably makes them feel abandoned when they see people leaving and it makes them question themselves. It's easier to jump in and try to undo the change they see in someone else, rather than look inward, which can be scary if you haven't done it in awhile (or ever).
IMHO, their visits are mostly about them, rather than out of concern for you.
