Would you confess, "sorry I'm being realistic... I hate realistic attitudes and try not to be that way..."
One could equally say, "sorry I'm being a booster... I hate boosterism and try not to be that way..."
I think the test for publishing on free Republic should be, can we defend what we say? not whether we are politically correct.
Sorry I'm being preachy... I hate preachiness and try not to be that way... 
no, because i don't hate being realistic... nor do i hate being an encourager... but being negative, yes--i must apologize for that... i hate being negative... especially because i cannot back up what i'm feeling... what i'm expressing is just a feeling... i have nothing to back up my negative feelings... therefore, i'm sorry... i hate having a negative attitude and try not to be that way...
i hate your preachiness too... and i don't believe you are really sorry for your preachiness toward me... in fact, i believe you like being preachy... i don't find it helpful in this case... nor do i find your "test for publishing on Free Republic" helpful... if i were claiming fact in a situation, then yes--i ought to back it up... but i am sharing a "feeling... a dreadful feeling" in my opinion, and not only will i not back it up, i simply cannot... which is why i must apologize for my negativity... it's my own feeling... again, sorry i'm being negative... i hate negative attitudes and try not to have one...
