There is no Torah knowledge without learning general knowledge.
Wrong. It is the other way around. Remember – reishis chochma yiras Hashem.
If you do not have a strong grounding in Torah knowledge, you will not have the tools to differentiate between valid general knowledge which brings you to a greater understanding of the Creator (or is just what you need for parnosso) and the universalist, anti-Torah brainwashing that you can be subject to in a university setting.
