That's certainly one perspective that many people share. As I said, my perspective was overruled by consensus. I mentioned in some comments here that I may have been wrong and the right choice was to exclude them.
However, the flip side is once we make the decision that some people are okay and others should be excluded, how do we prevent that from becoming a slippery slope? Who sets the criteria and how is it ratified by the community?
you are right in that you have to go by your conscience in making these choices; however, I think we all need to be more harsh in making those decisions with known bad actors
