That is a matter of opinion that reasonable people disagree about.
Again, people are inseparable from their ideology. If you don't like hearing about ideology (like I don't like having to see crucifix necklaces), avoid people and you won't have that problem.
And that's another issue is that people aren't so one dimensional. For example, many BLM people aren't on the LBGTQ train. Many Trumpers aren't antivaxxers. Many Libertarians aren't anarchists. Point being, there's not a ton you can draw from a crucifix.
As for the movie, CP Ellis is the man's name, if you care to read about him.
You can't separate people entirely from their ideology, but you can separate them much more than we currently do.
(For that matter, which "person" is the go.dev website, that we cannot separate ideologies from?)
