My "venting" mechanism from FreeRepublic is right outside my door - there's plenty of tree limbs and land to clear on my property, plenty of wrenches to turn, etc. I've also got a video editing project I'm working on, but that has been known to raise my BP much more quickly than anything I've ever read on FR has ever done. And the best part is that none of these remedies which work for me involve slandering other people, disparaging their character, organizing and plotting personal attacks on others en masse on thread, etc.
Life is simply too short to devote my entire life to what other people on the Internet say and think about me, or to turn it into some sort of crusade. I say what I have to say, and people can take it at face value, ignore it, or think that I'm an idiot. Any of those options are just fine by me, but I will still say what I have to say.
