A couple quick points:
No one should hesitate to share their opinion of a course, a photo, a technique, a theory, whatever - just be prepared to explain your rationale.
Disagreement is not bashing. At least not always. Don't expect universal acceptance of your opinion any more than you would universally accept others. There was disagreement over the Black Rock images (I know, I was one of 'em), but little that even approached bashing.
And the only people who get shouted down are the people who don't argue their position. Look at Matt & me. We disagree all the time, we shout AT each other plenty, but I don't think either of us would feel that he was shouted down. I know I don't, and I can't believe Matt would say he's shouted down either. We just have different viewpoints and repeatedly try to sway the other, generally to no avail. But, hey, that's the essence of discussion. As long as we try to avoid personal insults - and throw in an apology when one of us crosses the line - I think there is much to be gained over such disagreements.
Lastly, did it ever occur to the people who cry bias that maybe Tom's courses are simply better, in the opinion of posters in an arena that is highly subjective. I'll be the first Doak butt boy to proclaim that I have no real desire to play Stone Eagle. Maybe I'll get there someday, but I have a sneaking suspicion it is probably not much more suited to the bogey golfer than Black Mesa. I've already said I have no real desire to play Cape Kidnappers due to my problems with heights. Maybe, just maybe, when I praise The Rawls Course, it's because I genuinely loved my round there and genuinely loved the course.
Why do you assume that you can be objective, thoughtful and non-biased in your likes and dislikes, but do not extend the same courtesy to others? THAT, my friends, is bias, not the preferences expressed by many on this site.
