Only if someone posted
Nah, if some one's boss, or all their working environment consist of the people who one would justly describe as a regressive left. If you for example (just to fit in) haven't let them know what you think about certain issues or about their idiotic ideology, its a very reasonable to think that you could expect backlash or other unpleasant consequences if such a deception would be discovered. Especially that those are regressive left's people - they're vindictive and close minded.
calm and coherent presentsaiton of honest opinion should not trigger all the bad things you claim would happen
No, matter how you would present yourself on this forum, how reasonable, logical and honest you would be, its about what you say not how you say it. What is that hard to understand>?
It certainly would not serve those whose main reason for being on the forum is to bait, provoke, snoop, pry and cyber-stalk other posters.
You're being bullied and trolled and you're being played like a fiddle . You're letting yourself to be drawn into useless and pointless exchanges with someone who play dirty and there is no way you could passible win playing fair.
What more that is annoying you and you start to rant and rage in righteous indignation which makes them laugh at you even more. What more that encourage people like Harry to do more of the same.
Either learn to play the game or ignore him - those are your only options if you're bothered by Harry.
all the bad things you claim would happen
I'm not saying that all those bad things will surely follow. I'm saying that they might happen or some of them might happen. Don't forged about nutters too. They exist in the real world.
This is a limited-access forum so the whole world wouldn't know who swas posting what.
Polonius you have just proved that you know absolute nought about the Internet. Not only all the world would be able see those names and what was posted by them but you could very easily find everything that is available in the cyberspace about that person.
Limited access. Poor Polonius.
