In response to the original question, no, it isn't. If I asked the same question but substituted "religion" for "racism", how would you feel? I'll let you sort out the religious oppression perpetrated by the RCC and other religious institutions as a homework assignment. You don't get to only ask questions, you have to answer some, too. If you're not Catholic, just know that that is where xtianity started, and all you splinter group members share the blame for what they did before.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
