Gentiles have to respect and honor orthodox Jews. This is absolutely true. But there are many secular Jews. Sadly, Many of the prominent atheists are Jews. For example, Sam Harris, who is one of the most popular atheists with Richard Dawkins, is Jewish. Do we Noahides honor him, because he is a Jew? Or do we have to despise him because he is an atheist? Thank you.

Question
If one is trying to daven mincha before sunset (the time that would be 18 minutes after candlelighting if it were a Friday), and he barely misses this time, and there is still some visible daylight in the minutes that immediately follow, is he still permitted to daven mincha then? Or does he wait until maariv and recite maariv amidah twice?
