I believe the best rule of thumb is try not to post something that another pot lover could be offended by. I try very hard not to do that purposely and I'm getting better. I honestly couldn't give a rats ass where someone was born, the color of their skin, who they want to rub uglies with or even their politics or religion, or lack of it but as a HOBBY site the common theme is the HOBBY and anything that takes away from the unity of the membership of that HOBBY should never be allowed or tolerated, imho: BUT, we all agreed to follow the site rules when we joined so there's really no excuse.
Can't we all be adults and talk about these things like Civilized people? NO!
Politics and Religion have started all the wars throughout history and will continue until the end of time, I'm pretty damn sure so these ideas and strongly held beliefs will always clash and divide people and is the reason Civilized People have learned these lessons from history. While most of these Civilized People also strongly believe in Freedom of SPEECH we also know what happens when allowed to come between people and why every hobby group I've ever know has these same rules. So do some families during gatherings because of the friction it puts on the whole group.
So, let's focus on why we're all here and leave the divisions for other outlets and rally around and assist everyone here doing and learning how to grow, process and use this incredible plant. Cause honestly it's the reason we joined this site
