You don't, actually. What you know better than anyone else on this site is the sect you grew up in, which taught you to hate the outsider, which you responded to by rejecting the sect but not the hate, so now you use the exact same hatred and dismissiveness you learned at your parents' knee to lash out at that tribe you're still oh so very angry at without noticing that it impresses no one, gets you no bonus points, and accomplishes exactly what your tribe wants, namely giving them more reasons to be hateful insular bigots. Every time you assume that your prior experiences give you credibility to run roughshod over arguments, you presume that no one has had your experiences, no one has been in your shoes, no one has gone through your shit or else they would have arrived at the exact same conclusions, obviously. No. I lived among your people since I was fuckin' born. Difference is, they hated me from the get-go. But you know what? I'm 15 years older so I'm over it. Lets me see more clearly. When I say "I know X better than anyone on this site" I give it a lot of forethought, rather than presuming my depth of emotion equates to depth of knowledge.I know republicans better than anyone on this site.
