Yeah I know what you mean. I have a few members of my class who happily say they want to be party members. Probably some more who do and don't say it. When I first got here a fellow teacher told me to look out for the student who turned up to every class and took more notes than anyone else ;)
The Student tutor who all the students go to if they have any issues is a fully paid up card carrying member, so I do watch what I say around him.
So far I've not had anyone bring up the 3 T's but I've had one guy talk about wanting to go to England and the US as they are "freedomlands". I just gently change the conversation. For all I know he's one of the commies testing me ;)
