BRF is not a democracy. The mods' decisions are final, and all the rest of us are okay with that. Those are the terms of the "service." Many of us (me included) found this out the hard way.
Mods don't offer reasons for post deletions to any of us other members, it is done upon their discretion. Just like judges in contests don't offer reasons to each participant as to "why did we pick that entry for first prize instead of yours." Judges' decisions are final, and that is made clear before anybody even enters the contest. Same goes here.
Mods aren't trying to be fair to members, in fact, many of their decisions are pretty unfair to members. Mods are trying to keep the forum safe from litigation, keep threads on topic, thinking about what kind of message is going out to the world through lurkers and even unsavory members.
Like I said, the rest of us members have learned to live with the occasional unfair mod decision in the larger interest. I suggest you do the same, if you want to continue on the forum. Take your cues from what gets deleted, and don't post any more along those lines. Just like all the rest of us.
