Not a lecture. You agreed to the 6 Rules of Use when you registered.
2. DEROGATORY COMMENTS TOWARDS OTHERS
Tread lightly: "to speak or behave carefully to avoid upsetting or causing offence to anyone"
Tread lightly when you use my site and play by the rules you agreed to. We have a ranking system here. You are in the mail room, the member you cast baseless aspersions on has 5.25 years and 2,100 points on you.
Until you earn a higher ranking, tread lightly. Simple as that.
