I'm certainly not going to tell people what they may or may not discuss. I will state my opinion though. For example, if people are discussing Easter bunnies, I may state that I prefer yellow Easter bunnies to green Easter bunnies. I do. Its a personal preference thing, but I certainly don't think EVERYONE should prefer yellow Easter bunnies, or that green Easter bunnies shouldn't be allowed.
Everyone has opinions, and I don't mind expressing mine, but I do usually try to let people know it IS just an opinion. I remember, long ago on another forum (a very nasty forum) getting jumped on because I failed to provide a link to my opinion LOL! I simply told them my brain had not gone online yet, and I was unable to provide a link to my opinion at that time.
I LOVE differing opinions and open discussions, I find it very interesting. If everyone agreed with me, there would be no point to being on a discussion forum. On the other hand, although I haven't seen it here, I hate it when a civil discussion gets turned into a heated argument with name-calling and personal insults. On the forum where I am an ADMIN, that is NOT allowed.
