John Barrowman has been sharing the negative comments he received after his gay kiss at the Commonwealth Games opening ceremony in Glasgow on Wednesday night.

The 47-year-old stage and screen actor snogged another man as an act of protest over 42 of the 53 Commonwealth nations having homophobic laws.

And he has been dealing with the backlash on Twitter by outing his attackers to expose their "nasty and negative" comments.

He wrote: "I am retwtin the neg because I want u all to see how bitter and Nasty and Neg some people r:) I am so happy right now. Jb

"I'm Scottish and u can never take that away no matter what your politics are. Bitterness makes u ugly and old very fast:) happy jb"

He also answered some of his critics directly on the social networking site.

One user wrote: "please please vote for independence so we may be free of you"

And Barrowman responded: "you will never get rid of me:) enjoy the night don't be an asshole. celebrate Scotland. Jb"
