A big issue is different people have different definitions of these terms.
For example, say a very religous conservative doesn't want to use a trans persons preferred pronouns as they consider said pronouns to be untrue and sinful. They are otherwise polite and nondiscriminatory (e.g. they will listen to and implement ideas from the trans person and don't bring up their opinions of trans issues). Is this bigotry?
Or say some people in the company want to run a BLM donation drive and a conversation then ensues where someone states that they don't think racism has anything to do with USA police killings of blacks and it's actualy down to problems in the main african american culture. Is this racism?
