Personally I don't spend time and effort to find offensiveness in things - but I'm interested in being informed about the world around me.

For example, I've always found it easy to hail a taxi; it wasn't until a few months ago I learned it can be hard to get a taxi when you're black.

That's information that can be useful if I'm travelling with a black friend or colleague; or discussing the merits of electronic taxi hailing, or the place of taxis in a public transport system.
