When people start calling you names, it ought to be a time to pause and reflect. While it isn't nice, names often their basis in some degree of truth. I've been called far worse things than "Chamberlin" and thinking about them made me realize that most of them had some amount of truth to them - so for the ones that reflected something negative to me, I tried to modify my actions and words accordingly. If it is something I didn't find negative, I just ignored it.
So if you do not wish to be called Chamberlin777:
1) Stop being so vocal about your political views
2) Modify your political views
3) Show (in the politics forum) that you don't actually believe in the political views that you are accused of holding
4) Realize that those are you political views and say so what to those that call you Chamberlin777
