Left leaning people do too good a job of shooting ourselves in the foot by alienating people who don't 100% prescribe to the same beliefs we have. The reality is people are all over the political spectrum and that's not always a bad thing. Finding common ground and working together is what governance is all about.
Nah right wingers don't give a shit about purity testing. Evangelicals don't give a shit that Trump isn't a Christian nor do Nazis care that Cruz is a mexican-Canadian. If you're pushing in their direction thats all they care about.
Purity testing is a uniquely leftist problem and it's part of why it's so damn hard for the left to organise and accomplish anything ourselves much less appeal to the broader public.
The FBI has literally exploited this to destabilize activist orgs since the 50s with COINTELPRO and likely long before that.
If you go far enough right, you will find it. Trump once gave one little nod to encourage his supporters to get the covid vaccine, and they turned against him. He quickly let the news cycle pass and everyone forgot about it, but apparently that is the line they won't cross with him.
I should have clarified, but yeah I'm not discussing US right wingers, they are in wacko mode and follow no logic. The comment I replied to was about the left and I was discussing the center to left spectrum
