I see this quite a lot in a fairly supportive group I belong to.
Lots of people dispelling the myth that asylum seekers are raking it in, taking jobs and benefits, etc.
A positive space and then someone comes in saying "if you are so supportive of asylum seekers, how many fighting age men do you have living with you?"
It really annoys me! It's possible to be supportive of a cause without actually taking people in.
All I can think of is really rude responses, I'd like something measured and decent and not allow them to get away with shutting people down with that.
(and I know I'll get negative responses to this post, but I will be super grateful to anyone who can come up with something I can use)
