has anyone actually changed a racist's mind with a verbal or textual argument? has there ever been a nazi who was confronted with evidence that contradicts their beliefs, and, like Skwisgaar Skwigelf, just shrugged and said "Well... maybe I'll re-evaluates my life." ?
In public discussion it's not just about changing their mind, but also anyone's who's listening/reading. On any given subject majority of people are not going to do their own research, they will trust others to do it for them and believe the most convincing argument, based on their experiences(this is good btw, it's what got us out of stone age), so if you see a convincing looking argument that you can convincingly rebut, you should. Bonus points if you find a logical contradiction! However if it's some incoherent spam that doesn't even try to convince anyone, I think it's safe to ignore.
