Well, hang on, I’m parsing my words real careful. I support people seeking out training, but I don’t see how it can be REQUIRED, on both 2A grounds and practical terms as well. Is that what you’re saying as well?
NO state requirement for training, but it should be up to the individual, and here in Oregon, there are many great non-state sponsored training courses which teach the firearm basics and conceal and carry law.
As an aside, even here in a blue state, our state Constitution states that except for Federal buildings, no entity may prohibit licensed CCW holders from entering premises, ie. public schools, airports, etc.
