Hey, no one is judging you. I can only tell you how l would feel. Everyone is different. We all have differing opinions, that's what this site is all about.
Would you be happy if, (I need to be careful here), your brother 'allegedly' got involved in this sort of thing? I certainly wouldn't. Mud l'm afraid, sticks.
Admitting he is related to Chamal, and changing his name to Fenelon will do him no favours. That man was an absolute handful, and l mean OFF the pitch, not on.
