That's a ton of effort. And often I do want to follow someone for their tech content, I just don't want their politics.
For example, DHH was a brilliant programmer who created Rails. I say was, because now he is a self-admitted white nationalist. I no longer care about his technical work or opinions, because if he has ventured so off-course so as to convince himself that white nationalism is worth supporting, I must necessarily question his judgment on technical matters as well. To tolerate his white nationalism and continue to promote and condone his work would be helping to further the spread of white nationalism, which I find abhorrent and unacceptable in any form.
Trying to prevent further division is completely reasonable when you're talking about opinions like "we should have lower taxes" or "we should spend more money on schools." It is not reasonable when your political opponent literally wants to do genocide.
As I said in my first post, wanting to exterminate people of a certain ethnic group is certainly over the line for me. Similarly, openly expressing support for the fascist paramilitary force who are murdering people in the streets of my country is also over the line. These don't seem too troublesome for me.
