Wow... you really are a live one aren't you?
Now pay attention... I am only going to explain this once.
Between 1842 and 1844, Charles Darwin outlined his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved". The concept was simple but powerful:
individuals best adapted to their environments are more likely to survive and reproduce.[1]
Now... if that is too difficult for you to understand, here is another angle... maybe you have heard of the Darwin Awards? The Darwin Awards are tongue-in-cheek honors named after evolutionary theorist Charles Darwin. "Awards" have been given for people who "do a service to Humanity by removing themselves from the Gene pool", i.e., lose the ability to reproduce. It is for people who kill, or in rare cases, sterilize themselves accidentally by attempting to do stupid feats. You can review some examples of these awards at:

What was essentially saying was... if you want to dress like a thug, you increase your chances of early loss of reproduction (i.e. "sterilize themselves accidentally by attempting to do stupid feats" (or putting themselves needlessly in harms way)".
Your feeble attempts to discredit and put me down only reflect your own deficiencies. Like I said in my previous response, I do not disagree with you. I am making a different point that you are trying to manipulate because you obviously like to argue. So have fun arguing with yourself… I have made my point and am done with you.
