As for halacha requiring Jews who own businesses to give preference to hiring Jews. Dina Malcusa Dina.
DDD isn’t m’chayyeiv you to hire/not hire anyone.
If you choose to live in the USA you agree to abide by the laws. This isn’t Tzarist Russia or the USSR where Jews were kept in by force. If you don’t like the laws, work to change them through the political system or leave.
Besides for your logic, or lack thereof, isn’t the subject at hand which of the two philosophies–liberalism or conservatism–are better? In which case, that response to Avi K, who was criticizing certain laws, was either irrelevant or inadequate, or both.
No one’s forcing you to post in the coffee room. If you don’t like the posts, either get the mods to delete them, or leave.
