I've been confronted many times by people wishing to "save" me, and the ones that annoyed me the most were the pushy, "holier than thou", ones convinced that their belief/slant was the one and only way - no debate!... you know the type.. fanatics...
So don't come up to a GLO house to save them from their pagan ways...
Don't barge into a Hillel meeting to hand out Jews for Jesus material...
Don't stand outside the Catholic Centre on campus telling people that by supporting them you support child rapists...
and most importantly don't stand outside classes that deal with evolution holding a sing-in to save our souls...
Other than that if you aproach wanting to discuss religion and faith... and I'm in the mood... no problem... just be certain you have your facts straight before "confronting" me with the "falsehoods" I live by
