Q: What's the difference between the following examples: Neither of my teachers are mathematicians. None of my teachers are mathematicians.

A: Neither - not either - implies that there is a choice of only two. So 'neither of my teachers' is only correct if there are exactly two teachers, 'none of my teachers' can be any number

Q: Maybe this question is too simple for this site, and I should post it on the english-learners-site, but I will give it a try. Lets say we have 3 scenarios: A person who hates all followers of a specific religion, no matter what their background is, but otherwise likes people of all skin colors and origin countries who are not followers of a specific religion. A person who hates all people with a specific skin color, no matter what their background is, but otherwise likes followers of all religions and origin countries who do not have a specific skin color. A person who hates all people from a specific country, no matter what their background is, but otherwise likes followers of all religions and all skin colors who are not from a specific country. 'Hates' in this context means believing they are worthless, being prejudiced against them, generally discriminating against them, bad behaviour against them, and disliking them. 'likes' just means the opposite of my explanation above. So, based on this definition of the word racist: The belief that race accounts for differences in human character or ability and that a particular race is superior to others. Discrimination or prejudice based on race. Would you use the word racist to describe the person in all of the 3 examples I gave? Or are there better fitting words for specific forms of discrimination? Particularly for the first scenario (religion specific racism). I am looking for a better word to describe such a person. Religion is independent from race, and I am not sure if only country of origin is enough to relate to a specific race so that the word racist could fit here. Skin color is more obvious, but there could also be some discussion if a specific skin color already suffices to assign something to a specific race. (I am not a native english speaker, so sorry for any mistakes and if this is obvious for native speakers.) Edit: This question may be related to this Question and this Question, but I dont see it as a duplicate at all, because there are various different aspects in the question and answers. Also i could not find the questions by search before i wrote my question, maybe some of the answers and aspects are similar, but the questions itself are different in my opinion. But that is only my opinion, feel free to close this, if you think they are too similar. I got some useful answers already, so I dont insist to keep this open. I will accept the answer with most votes at the weekend, so the community decides which answer fits best.

A: Bigot is the term that you're looking for. bigot: a person who strongly and unfairly dislikes other people, ideas, etc.; especially: a person who hates or refuses to accept the members of a particular group (such as a racial or religious group) - (Merriam-Webster)

Q: I overheard my manager asking 'What are you up to?' What does that idiom mean? Is it an informal/negative way of asking??.

A:
'What are you up to?' means 'What have you been doing lately?'. If you add an adverb to the end of the phrase, for instance, 'What are you up to tonight?' or 'What are you up to this summer?' it can be interpreted as 'What are you planning to do tonight?' or 'What are you planning to do this summer?'.
