Ignoring the racism aspect of your post, there are of course people who love to take offence at everything. I remember HR sending me an email after I used 'brain storm' and someone complained it was offensive to, no idea but they obviously didn't like it.
I remember my husband's Aussie friend turning up one day saying, "Oh the Pakis are coming. Going to be great". To him, Paki meant, very specifically, people from Pakistan and was no different to 'Brit or 'Scot', for example.
The adage, if you don't have anything nice to say, keep quiet tends to work.
On the whole it isn't difficult to avoid causing offence. If someone takes offence at something like debbriana's example then I do think maybe the offended party should accept that there was no malice and get on with it.
Remember that MN tends to home the perpetually offended or at least, a higher percentage than you'd meet in daily life.

Some of those questions are stupid, of course. Some of them are surely genuine questions and I'd quite like to know the answers.
Yes I wash my hair - why wouldn't I? (was it braided?)
Yes I can straighten my - why couldn't I ?
Do you bloody wonder what your hair would look like as an afro
^^--- I have no idea because afro hair is different to other types of hair and I've never been told the answers. I've wondered what my hair would look like blonde, afro, short etc.
Do black people feel heat in the sun - yes
^^---- clearly stupid
Can black people tan - yes. Dark people can get darker
^^---- vaguely stupid
You don't sound like a black girl
^^---- ignorant and very stupid / racist
Where are you from? / and your parents?
^^---- an example of you looking to take offence.
I asked my brother if he had to put suncream on his newly adopted Ethiopian son. How would you class that?
You comment about your husband smuggling your boys out of Ethiopia made me smile being so relevant to my nephew.
