Richard English made me very upset and I want to tear his eyeballs out for what he said to me what to do?

A guy named Richard English told me I am commiting suicide he said I drink too much he said a 750 ml's bottle of wine every friday, saturday and sunday is too much or a 1 liter bottle of tequila rose or 1 liter bottle of hpnotiq or 750 ml's of Nuvo or 375 ml's of vodka. He said any of those bottles every friday, saturday and sunday is drinking myself to death and he shouted with capital letters "YOU ARE KILLING YOURSELF IF THAT'S WHAT YOU WANT TO DO THEN NO ONE CAN STOP YOU JUST DON'T TAKE YOUR ANGST OUT ON ANYONE ELSE" and I really want to know why this guy told me I am drinking too much when I went to his profile and opened up some of his questions and saw other responses he wrote to people. One where he said that a person can drink if they are over 5 in the UK as long as they do it at home he even said he drinks himself and started when he was 5. He even told someone they can drink all they want if they are underage as long as they do it in their home. I also saw how he responded to a guy who asked whether it was safe to consume a bottle of red wine daily he responded to him to either have half a bottle of wine a day or take a few nights off each week and "you'll be fine". While he responded to my post that i am drinking myself to death with three bottles of wine or other in a week I really hate the ugly old man he's so unfair and I think he's a jealous piece of sh*t because I am young and he's nothing but an old piece of trash with all his youth behind him. The guy is 69 years old and probably jealous of a young 24 year old and wishes he were me thats why he is insulting me. I think that's the real reason, anyways I can't wait till this old man dies I would go and piss on his grave what to do now though while he's still alive????
