Well, firstly, I would never seek to sneer at, or ridicule, anyone for a mistake in spelling or grammar. Firstly, that would reflect more discredit on me than on them, and secondly (as I pointed out in an earlier post) that sort of thing is a double edged sword, and there will those more erudite and fastidious than me (I? - see!) who could have a pop at my own errors.
I pointed out a little spelling error to a poster who was dismissing large chunks of our fellow citizens and humans as morons. I was simply trying to illustrate that we can all make errors, whether large or small, and it's dangerous to simply dismiss great dollops of society as moronic. Let he who is without sin cast the first stone, and all that....
I became negatively inclined toward you when you made no attempt at reasoned discussion, but simply came out with some tribalist slogan in response to my post, and then had the nerve to call that a 'lesson'. I mentioned your lack of grammar (and possibly I should have said, 'punctuation' - we're, none of us, the fonts of all knowledge), because you made zero effort to conform to the written communication protocols that everyone else does. I don't know you, so can't say whether that's because you're too idle to bother, or think that you're too important, but I hardly think that those are ideal qualities for someone attempting to hand out lessons.
I stand by my original point that political change won't be achieved by getting into an aggressive frenzy amid existing fellow thinkers, but only by reasoned pointing out to others where they've gone wrong.
