bless their cowardly heart

I've just received a comment on an old blog which indicates that my son and I are mean. The subject matter was around laughing about a rather wide woman who blocked the aisle at our local supermarket and yes, it probably was mean of me to say stuff but it seems strange to tell me I was wrong by 'name calling' my son and very wrong indeed to do so anonymously.
I am who I am and I'm certainly not perfect in any way but I say what I say openly
