Well I can only speak about myself and my questioning someone's claims and expertise if someone's claims and expertise do not add up or if say someone uses a term incorrectly but insists it means that . By the way tez I miss your get backers avatar from way back then!
Oh you are not rude at all! I'm not saying one shouldn't question but getting angry and spluttering bile over everyone is just so not the way to go.
I'm not quite sure which avatar you mean but I was meaning to change the 'thin blue line' one about now, let me know and I'll see if I can find it again.
