WP's PPR forum isn't for the weak of heart, or those that are easily offended. I kinda think of it as a "post at your own risk" place.
I like it for a lot of reasons... I can throw out an idea that is bouncing around in my head, and just sit back and wait for someone to find all the flaws in the idea... which I can then use to make the idea stronger... or discard the idea altogether if appropriate.
I also feel I can speak my mind, say what I want, not have to worry about it, people won't come here if they're easily offended, or at least they shouldn't. I'm not easily offended, truth might hurt, but i'll drink deeply of that cup every time.
Few here share my opinions either, at least not on the specific levels, I suspect a good number do on the general levels. But I can say that this forum has helped me greatly to come to grips with many of my ideas and philosophies in life. I think I am a better person for having read and posted here. Better or worse, there is no doubt that I am a different person. And I like today-me better than 3 months ago-me.
