If genocide is a red line for voting than every citizen who has voted within our life time would have crossed it. Our whole political system upholds genocide from local to presidential. A red line and acceptable are not actual synonyms like you are inferring. I do things I don’t find acceptable all the time because they are better than the other option and its less acceptable to allow the alternative to happen. I can have gencodie and fascism in america or just genocide. Neither is acceptable. One will happen whether I make a decision or not.
