Your comment isn't in earnest, nor is your sadness real.
I am sympathetic toward the feeling of "hey, this isn't something I can just look past and Enjoy The Fun on". I think that's a reasonable reaction! But I also think taking that as a cue to skip a particular thread is a healthy choice and a reasonable community-minded expectation.
Shutting down UK political discussion in a thread which to all intents and purposes is about UK politics reinforces the idea that MeFi is a US site for US people, that our country's culture is just entertainment and those of us from outside the US are just guests here.
