How do you respond to people who try to dictate your political/party affiliation cause your views don't 100% align with theirs?

I've been a Democrat all my life, have my voter registration and voting record to prove I'm a Democrat, but in todays political world that's not good enough, you either support the Democratic party 100% in every thing they do and believe or fellow Democrats attack and accuse you of of not being a Democrat or a Republican. Same thing happens on the Republican side, you support the Republican party 100% or you get labeled a RINO/Democrat. Far left and right extremist have taken control of both parties, and if you don't 100% support their extreme views, your instantly labeled a fake Democrat/Republican even when your registered Democrat/Republican and voted Democrat/Republican.
