It happens in every corner of this place. Main board, OTW, PPP, everywhere. It has probably happened to 90% of the people on all of those boards. It happens in a joking manner, as a way of making a counter argument, albeit often lame, and lots of other ways. A lot of people do it from all political persuasions and football opinions. I've probably done it, but not a lot as I find it pretty goofy so on that I agree with the OP. I'm not sensitive enough about my opinions to be afraid of any particular type of counter argument. The OP is apparently hypersensitive.
The premise that anyone would read a post that says FIFY and assume the quote above hadn't been altered defies logic.
If there is an issue or complaint to be had it would be with the software that allows quotes to be altered. It is board wide. To take that personally and threaten people with complaints to moderators is silly and sad. How fragile does one have to be?
I'm telling mommy. Nanny nanny woo woo.
For the record I haven't received my PM warning yet. I wonder if he went straight to the mods breaking his own iron clad rule.
