Guest from Sanity, you seem not to be aware of it - and I can't speak with finality for anyone but me - but here's the thing:

A blowhard is not necessarily disliked because of his 'facts'- when it comes down to it, we all like to believe we understand truth- but because his or her method of reporting that truth is so off-putting, so counter-productive we/I reject it. We/I tend not to listen to you because it is not worth it.

Whether or not you know it, you are not the whole repository of truth and facts. Frankly, often because of your pre-set mindset you are WRONG. And then because of your 'blowhardiness', every so often we/I miss even the kernel of truth and fact your post may hold. And then when you remind us - in a blowhardy fashion- that you have told us and told us and told us of your individual 'fact'... well, hell. You figure it out.
