You call it "prejudice", while I call it "experience." Since you seldom deviate from arguing "straw men", I find it mostly not worth the trouble to bother with you.
And by the way, your comment above is another "straw man." You are falsely coloring a disinclination to argue with you because of past experience, with the word "prejudice" which has deliberate negative connotations associated with being unfair to someone.
No, you've had a hearing, you aren't being "pre-judged" you are "post-judged", and my judgement is that you seldom say anything worth rebutting.
If it walks, talks, and acts like a duck it isn’t a goose!
Besides if you really thought it was vain you would just pretend I wasn’t there.
You set yourself up as some big authority when in actuality you succeed in being some big pompous self-filled clown.
