Homework

The Line is a call-in show that deals in secular humanism. The hosts are all atheists but they argue for compassion and dignity for all human beings from the perspective of rationality. 

Predictably they get more than their fair share of oddball callers who are ill prepared and with little to no critical thinking skills which makes the hosts' job easy if a bit frustrating. People will hang up or get boisterous when you have cornered them with rational arguments. 

The hottest topics are religion and (you guessed it) transgender issues where one particular host with a doctorate in biology surgically goes through the arguments for the validity of transgender people. He never successfully gains converts but if nothing else pins them down with a wrestling move where they can claim a tie even if they have lost the match. 

The problem is that people reach a desired conclusion and then look for evidence to substantiate it which never works. Yet it never stops them from trying. People don't like having their world view destroyed (no matter how unfounded) and it upsets them when you unravel it. 

While I am not an atheist and am indeed transgender I know well enough not to attack issues from completely the wrong angle and that you need to do your homework before making your claims.
