Speaking in hypotheticals does not indicate what I believe about their system of belief one way or another. From other threads, you know full well what my beliefs are concerning the future of Jews, Messianic or otherwise.
The Messianic view is either right or wrong. If it is a false view then we should say why we feel it is wrong. If it’s correct then we should all become Messianic Jews. Simply saying it’s “their opinion” isn’t a very convincing argument.
