I don’t agree. Words have meanings, to be sure, but I usually take the dictionary’s meanings as authority for the proper use of words.
“Hostility and ill-treatment, esp. because of race or political or religious beliefs.” (per Google)
If you’d like to defend the proposition that on the SDMB, Christianity is NOT subject to hostility and ill-treatment, please feel free.
I agree, of course, that the SDMB is not inflicting bodily injury, hounding people from their homes, or denying them job opportunities. But that’s not the limit of the word.
