I think I can count on one hand the Baptist Boarders who are moderate, moderate-liberal or just plain liberal.   All of them irritate the fool out of me, mainly because they are articulate, well-grounded in what they believe and engage in lively debate.  They make me work too hard.
The purpose of the debate forums is to debate, which starts with the presumption that there are differing opinions.    Shoot, the liveliest discussions we have are rarely conservative vs liberal.   They are conservative vs. conservative.  
Are those who disagree with me wrong.   Of course.   But heretics?  No.
Now, I have seen occasions when a young believer may come on here and espouse a view which he doesn't realize is heretical.   They have bought into some teaching which sounds good, but can't be supported by Scripture.  Some gentle correction is in order.  
I contribute to another Baptist discussion forum which is avowedly moderate-liberal to liberal, and a third which is unabashedly ultra-liberal.  
On occasion I will get involved in a discussion on those boards, but I'm not going to take my toys and go home because they off base and won't listen to me.    Shoot, I have too much fun making them uncomfortable.   In a gentle, Christian manner, of course.
