Most people are pretty rational, and have examples to back up why they are offended by something or why it can be deemed racist (as has been brought up in this discussion). Your argument is such a "slippery slope" logical fallacy. We are well aware that all situations can be looked at individually, and we also know when people are (generally) being rational and reasonable. I don't think anyone here has been irrational or unreasonable when it comes to the points they're making about how this can be construed as racist.
And again, it is not up for the privileged majority to tell a historically (and presently) oppressed minority what they should or shouldn't be offended by.
Also, in answer to your question, no. Because even if we are a minority to them, we have systematically oppressed and treated them like **** too. We as white people have invaded, raped, pillaged, appropriated, and stolen a lot of things from a lot of different cultures, and asserted our superiority in every instance we could, even if we are NOT the majority by numbers.
"Minority" in this instance can mean someone who as seen as "lesser", and even if they're a majority, trust me, white people see them as "lesser" people.
