I think people have misinterpreted what I was saying. I don't suggest that non-Jews are obligated to observe the Shabbat. Of course this is not the case, we do not impose our belief on those who are not Jewish. Non Jews have no reason to keep the Sabbath.
But the issue to me, honestly, is that by remaining open we are benefiting from work which is done on the Sabbath. Ask yourself why a Jewish store owner should close his store on the Sabbath. Every religious Jew deals with this problem, that by closing the shop on Sabbath they are losing money they otherwise would make on the day. Those Jews who open their stores on Sabbath are violating the Sabbath and being rewarded for it. The sages explain that any gains made by a Jew (financially or through labor) may only appear to be gains, but in the long run they are punished for their transgressing of the Sabbath.
We should protest people who open their businesses on the Sabbath, we should boycott them and should rebuke them. Some may consider this 'religious coercion' or whatnot. The issue is, to me, an issue of placing a stumbling block before the blind. Maybe a person born Jewish comes across this site and sees that we are claiming to be the followers of the great Rabbi Kahane, who to the best of my knowledge observed the Shabbat according to Orthodox standards, and he also encouraged all Jews to keep the Torah. We Jews who want to continue the legacy of Kahane must also continue the legacy of Shabbat observance otherwise we are not being true to the ideals of our mentor. When others see that we are continuing work on the Sabbath (while most religious Jews here do not use the forum on Sabbath even when it is open) they may be inclined to believe we all desecrate the Sabbath. So too we are sending a message to them that Sabbath observance is not important, and they may be fooled into believing that it is OK to post on the Sabbath as long as it is nationalism and pro-Israel...
I have no problem if others are using the forum on the Sabbath. I am certainly concerned that Jews are using the forum on the Sabbath and we are assisting in leading them astray of the way of the Torah.
