Even in my atheist group there are men that totally and inappropriately dominate group discussions. The females are clueless and don’t notice. It irritates a lot of the men.

Be yourself. If you have something you want to contribute, by all means do. If someone takes offense, you have several options: 1. Defend your point of view, 2. Apologize, 3. If other person is abusive, either block, or report to Administration.

Do whatever you damn well please. Be you. Don't worry about offending others, that's their problem not yours.
Welcome to the group!

Talk away !

Not sure where duct tape and sunflowers come in but say what you like. If someone disagrees expect a lively debate. Enjoy
