I keep hearing of what he's done to people, etc etc.... but I have yet to actually be told about what he's done to people.
I've talked about my experience with him and thats that. I'm sorry but to be honset you're just a name on the internet to me no offense. But this is a guy I actually met and had a good time with.
"To be forewarned is to be forearmed." Since you have had a good experience with Alex, you should go with that and enjoy the friendship. However, to employ another cliché, "Where there is smoke there is fire." I suspect Alex has at least done something to some people that has caused them to apparently distrust him. Speaking from personal experience, he has been fine towards me. I have no reason to not like him....he did call me gramps at least once if I remember correctly. That's OK though because I am a grandpa, although not his.
