I am a Noachide from the U.K. I visited the site yesterday (Rosh Hashanah) and noticed that there were unanswered / unfielded questions here. I thought to myself, 'If a Gentile has asked a question here, and does not receive an answer, then they may, in their ignorance, think Israel is ignoring them / shunning them without cause'. So, fearing chillul Hashem, I fielded a few questions. Only later did I realise that I might have been encouraging Jews to do melakhah on Yom Tov - I of course had no way of knowing whether the OPs were Jewish or not.
I'm very sorry for this. I thought I was being the hero, but may in fact have been a dolt. I've left the answers up, because removing them now may cause more problems ('Where did my answer go?', 'Why has my answer been removed?' etc.).
My question therefore is: Which is worse: the potential chillul Hashem that might arise if a Gentile doesn't get an answer here, or potentially encouraging Jews to do melakhah on Yom Tov?
As I said in one of my answers, I'd be happy to play the nightwatchman here, if such a thing is needed, and there is no one better for such a job. Might it be helpful if some Noachide were given a set reply, to cut and paste in a comment box on Yom Tov, to avoid both the possible sinful outcomes alluded to above?
