Someone started a thread on Brexit in AIBU, specifically explaining that she had done so because she felt the topic in question needed wider circulation. Up pops MNHQ to hide it safely away in the Brexit subtopic. Why??? This is something that is going to affect all our lives really very soon, and the one and only reason given by MN is that that area is quite active anyway. As has been pointed out, you don't shunt Trump threads off to Politics, stroppy teenager moans off to Teenagers, or Trans threads off to Feminism. So why?
