You're basically saying the entire civil rights movement was immoral because someone might have lost a days salary.
I don't think that's a fair comparison at all.
Surely there are times when civil disobedience is a good thing, but every cause does not equate to that.
While I agree with the BLM premise, they are not doing themselves any favors. People jumping in front of cars and claiming they were "hit", when in fact, they stepped into them.
That's not civil disobedience.
Also, the BLM movement is refusing to acknowledge that the people who are dying are committing crimes and that is the precursor to most of the problems.
Although, BLM has absolutely nothing with what is going on here in Oregon at the moment, and yes, these people, if they find themselves dead, will have no one to blame but themselves.
Taking over a federal building of any sort is going to go poorly.
