Dear Cook County: proselytizing is NOT mandated in the "Old Testament". You are twisting statements out of context, as is typical of people attempting to proselytize. Who is "keeping the light to yourself"? That is a ridiculous statement. Every religion should afford some "light" to its adherents. That's why they follow that religion. If non-Jews want to observe the 7 Noachide laws, which will elevate them, they can do so. But they are not required to convert.
You can go on and on, as you please, but it is untrue gibberish that you are attempting to sell as fact. Jews do not proselytize. And I don't have to waste my time justifying that precept to you or anyone else.
