"If you are going to go against the left, you're going to be bad as them! Ignore them and they'll go away eventually!"
"Stop fighting them, you're as bad as them when you do!"
"Don't fight back if you're white, you're just giving them ammunition about their white supremacist narrative! Stop it!"
I've seen this shit before and I'm surprised that people here fall for this, every, single, fucking time. It's nice to know that glowies have more power here to shut up people in a single demoralizing post, discouraged to fight back. So, good job on falling for the scheme, I guess. Big ups.
None of the examples you listed are defeatist, at least not in the way that many of us feel understandably demoralized.
All your examples are classic, dillusional turn the other cheek cuckservative lies.
You can feel demoralized by how bad things are while still wanting to fight back.
