nailit, I honestly would not judge anybody based on those things!
I did however make that mistake once. long ago I went to work for a taxi company, one of the first drivers I met was an overweight heavily tattooed skinhead, with tats all up his neck and across his knuckles.
Then I heard all the old ladies asking for "Mike" all the time, where is Mike, he usually picks me up, he always helps me take my shopping in etc. well of course, this thug look alike was Mike, he was the one of the gentlest and nicest individuals I have ever come across! How wrong I was to judge, this world could do with a lot more "Mikes" with or without the tattoos.
