user is at fault , here for example would it be fair ( NO OFFENCE SERIOUSLY) that if i got attacked by a black man or women with a weapon to say all of them are like this and there fore banish , or say if i got in a fight with a drunk irish men , say all of them are like this , or say all clean cut blonds are exactly like paul bernardo ? it is sad how people are yes but no it is not the companys fault now if they see this and ignore things ie

(FAKE ADD)
*wanting to meet underage women i am 64 want 13 year old*
