It appears that only one attempting to force their views on anyone is you. You are the one admonishing people for learning Yiddish. Myself and others are wondering why you want to exclude people for having the opportunity from benefitting from knowing Yiddish. A language that is specific to yiddin, hence it’s name.
And don’t start preaching about Sephardim and Spain, the overwhelming majority do not speak Spanish because Spain is Sefared. That is a inane comment. And if that were the case, the benefit of learning should have nothing to do with bring able to tell the goy that you need a bolsa. Which is what you started with.
1) typical of you to complain that others are “forcing” views on others when you are the one telling people not to learn Yiddish.
2) preferance for Yiddish over Spanish has nothing to do with anti sefardic tendancies. Preferance for Spanish over Yiddish would very likely be related to anti chassidic or yeshiva tendencies.
