I can't speak for all Reform congregations but you would never find pork served at a Wise Temple function, and this was the birth place of the Trafe Banquet.
However, offsite, all bets are off because it is what the members choose to do and this on occasion is a problem. Mostly, if folks care, the provide for kosher requirements, if they don't why are you there if they are Jews? If they are not, well, you have to know what to do with yourself. If you keep strict Kosher, nothing served in a Reform Temple will do anyway, regardless of whether the food is specifically trafe or not because it is rare for them to have the dual kitchens. Nevertheless, the Reform community is a wide dispersion of practice so that a goodly number do keep mostly kosher and this means that rarely any official event will create a situation where you are offered anything that is forbidden, but it may not always be kosher certified.
If you are orthodox and living and breathing in this world, you would know not to eat at a Reform function, any more than you would eat at the house of a non-Jew unless you knew specifically the situation of each dish that is being served. This is the basic challenge of Kosher, whether you are perfectly observant or kosherish.
In the situation of JStreet, this organization is at odds with the Jewish community as a whole even if leading members of our community are completely clueless about this. JStreet was already disgraced when they had to admit they were a Soros sock puppet. Why anyone expects any more than what you would from a room full of people who basically hate Jews is a shock to me.
Which gets down to why is the person who is writing this surprised because these folks don't even pretend to care about Jewish observance, they are evil. Gees. But, these are not representatives of Reform Judaism, so stop with the smears.
This Gentile has been studying Jewish dietary laws ever since I joined a Jewish-Christian dialogue group wherein the Conservative and Orthodox said simply that the Law is the Law when it comes to food. The Reform folks said that Kashrut was G-d’s way of providing for His people by specifying safe food preparation before the advent of modern antisepsis.
The Book of Daniel is also instructive. One of my Reform colleagues asserted that it encourages vegetarianism based upon Daniel’s culinary challenge to the king.
A coworker who took up Orthodox observance told me that yes, an hygienic kitchen makes ptomaine unlikely, but following kashrut brings one closer to the L-rd.
This Christian couldn’t agree more. Go figure?
