YOU made the disgusting comment.
Why don't YOU make a donation to the charity?
Your comment was utterly inappropriate, violent and directed at a woman. It wasn't funny. It wasn't meant to be funny.
What is darkly funny (not in a good way) is your attempt to wriggle out of the responsibility for your own words.
No among of twisting or sophistry can change that, no amount of posting little links will change what you said to a lady online.
Let me worry about my credibility. You worry about being an online coward and a thug.
