Toi, c’mon. I am very, very familiar with Birthright, the good and the bad. No one is ever forced to go to a bar. That being said, the rules they operate under, the insurance coverage they have, and the security guidelines they must follow make it impossible for people to take side trips during the 10 days of the experience. People visiting their non chareidi relatives would be prohibited as well. Also – the conditions or circumstances whereby a participant might be billed for the entire cost are laid out explicitly in the paperwork and application process before the trip, so there should be no surprises for anyone who bothered to read them.
Clearly, the majority of the participants on the regular trips are not only not frum, but are mostly far from any Jewish experience at all, especially those from the US, or places like CUba or Brazil. Such a group is not the environment for a frum young adult. The good news, such as it is, is that the statistics demonstrate that Birthright alumni are more likely to participate in Jewish experiences, date Jewish, and marry Jewish after their experience. That in and of itself is a pretty good justification of the investment when intermarriage is over 50%.
There are a few offerings for frum kids. I know, from having worked with the logistics provider for Birthright while leading my own, non-birthright seminar in Israel for student leaders, that they only do mehadrin kashrus on a “best efforts” basis, and all else is rabanut hechsher. It was somewhat of a headache for us, but we worked it out and found solutions. That wouldn’t be the case on a birthright trip, and it wouldn’t satisfy the needs of many. I don’t know what arrangements they may have made for the frum trips. But, again, they are upfront with it, and will tell anyone who asks what the kashrus standard is ahead of the trip, I think it might even be on the FAQ on their website.
