Interesting that at the exact point your examples break down, the contradicting evidence to your point becomes fundamentally "different" and you just dismiss it.
Besides, don't you know the animorphs? Birds can change into humans, andalites, tons of stuff.
Back to your point: a slogan does not gain validity or credibility by being false; it loses its validity and credibility by being fundamentally false.
You see that slogan as particularly important because you've used it before and because it's popular.
That does not make it a good or correct slogan.
It just makes the person saying it look like they're spouting gibberish since there are so many simple examples that prove it incorrect, many of those examples displayed in these threads given by the people myopically chanting that acab is valid.
I agree these discussions are important, but what hope do you have of influencing other perspective when your argument is, at its foundation, flawed and clearly incorrect.
Black Lives Matter? Undeniable.
Of course they matter.
All Cops Are Bastards?
Objectively false schoolyard taunt.
That backfiring banner is working against your point and against your credibility.
I dismissed houses because they're inanimate objects that we can literally break down and turn into something else. That thing would no longer be a house. And, if I DID think all houses were inherently safe, then that change would mean that I no longer think it's a fundamentally safe thing. There's no gotcha here.
I'm tired of the rest of this conversation, we're clearly at foundational differences in our world views.
Are you tired of thinking of all of the synonyms for a house that prove your first paragraph incorrect?
Our "foundational difference" relies on you actively ignoring the world around you and insisting that all humans are the same no matter what, and if they get a tattoo or hold open a door then they are no longer a human.
Not a strong or defensible foundation for your worldview.
It's merciful that you think of your self-Imposed limitations that way, but try to bear in mind for the future that with your eyes closed, you can't really tell what's going on around you.
