Depends on the critic..
And what I'm being criticized for

Been a long time since I actually heard truly constructive criticism

And longer, since it was actually relevant.

That depends on the delivery. If it’s constructive and meant to offer an honest assessment of weakness and/or a method of improvement, I’m all ears. If it’s simply meant to insult or tear down, they can fuck right off.

Yes very well from intelligent people but that leaves out perverted liberals / socialists lacking an independent brain and morals. I won't put up with brainwashed sheep.

If it's grounded, yes. If it's just random insults, no.

Not initially, it upsets me. Then I think about it and if it was fair I admit it, acknowledge it, tell them so and vow to myself to correct it. I fail often but all I can do is keep trying.

If its logical, of course

depends who is saying it and what is their intentions. I usually ignore or use it to better myself
