common, if you were doing it in violation of state low, then the irony of you complaining about someone else’s behavior is too much here …
but let’s ask the serious question – what is halakha when 2 people have different opinions and need to act together. Say, you invite me to your house and your food is perfectly kosher by you, but I hold by some chumros. Would you feed me the food according to your standard or mine?!
another way to look at this: you treat the person according to what he needs/wants. If you like to tell funny good-natured jokes, but you know someone is a sensitive person and will get offended – then, you do not tell him the joke. You do not say – my jokes are good, and he had to deal with it … Similarly, we support a poor person according to his former standard (if we can). Same thing here, you have a person who is afraid of something – why would you not accommodate him just because you have some machlokes with the government. Just show some chesed.
