I do give to transgender individuals. In our country, their rights are violated; they can't find jobs in most cases. If you remember, I once wrote about an incident when I had nothing to give, so I gave my packet of chips. I don't think that this is the right thing to do, but everyone has a belly to feed. If they can't beg or find jobs, they might resort to prostitution. For them, I believe begging would be better than being a prostitute. Things will remain the same until the situation of trans individuals and their rights improve.
I remember I was in a rickshaw (a vehicle), and a trans came to beg. I had no money, so I gave her my Lays packet. He/She was smiling while my vehicle went further away from him/her.
