I consider an organization on their tenets, under which Black Lives Matter is completely fine.
KKK for example isn't.
Right-wing terrorism has no redeeming kernel of decency, nor does it have a productive movement behind the (few?) bad actors.
No, you don't, or you would consider a religion that endorses literally infinite amounts of torture for anyone who disagrees with them to be violent. There's also its attitudes toward homosexuality (Leviticus 18:22), slavery (Exodus 21:7), murdering people for working on saturdays (or maybe sundays?) (Exodus 35:2), and touching pig remains (Leviticus 11:7), among others.
But to some extent I do agree with you, otherwise I would still be a Christian which I'm not, for the fact that any belief that subjugates moral philosophy and reasoning to interpreting holy text will always have blind spots.
Either way, I apologize if it distracted from the point I was trying to make, that all organizations, good or bad will have bad actors, but what's important is identifying which organization can be fruitful and which is inherently bad.
Maybe we will disagree on a few there.
As someone more eloquent than me put it: Christianity had it's chance to rule the world; we call it the Dark Ages for good reason.
