You still haven't given any indication that you underand the weight of the term "lynching". If you'd like to, maybe start with this slim book, which I found sobering: https://www.amazon.com/gp/product/0933121180
The only example I can think of where someone lost their job due to a donation was Brendan Eich, whose political cause was changing the constitution to strip a civil right from LGBT people. You are worried about the effect on his family, but he was literally trying to harm hundreds of thousands of LGBT families, and the LGBT families at Mozilla were very reasonably afraid of more direct harm.) Why are you concerned about only one kind of family?
(And I'll note that if his career has been harmed, it's hard to measure. He's the CEO of a company with $42m in funding, which doesn't sound like death to me.)
Your taxonomy is also suspicious. The problem is not people having opinions; it's them acting upon them. And make no mistake, political speech is action. The whole point of it is to change society. That's why we protect it so fiercely under law: its enormous power to shape democracy for the better.
More than that, your dudgeon here is anti-freedom. If people don't want to work with Eich, who are you to tell them that they have to? He gets his freedom of speech; they get their freedom of association. If you don't like that, you get to exercise your rights to speech and association.
Of course, if you really wanted to pursue that, you'd have to end at-will employment. It would be an interesting world where nobody would be fired for a political opinion. But it would require absolutely massive government intervention in employment, so I doubt you'd find many conservative backers.
