As I’ve said before, even if refraining from indulging in everything you see is not considered a chiyuv, by having such a dinner an organization and its rabbi are essentially saying this is OK. Which is essentially not OK.
I don’t scream at people for not being on a high level of yiras shamayim. I am definitely someone who is severely lacking in the midah of not being a behaimah. But I am also someone who admits and knows there is a problem and I strive for reaching the true level of being a mentsh. And i believe when truth is being spit on i should stand up for it. Sorry but that should not be considered feeling holier than thou.
