Wait, I think there might be some UK English to US English language barrier going on here.
By "considering" I meant "taking for granted that"....
To clarify my argument, the statement made was:
Gun availability generally, is a problem.
I agree with that point, but since, or "considering" that an all out ban isn't possible to curb gun violence generally, we have to look practically at specific types of regulations if we reasonably expect some action on curbing shootings of the type we're discussing.
Does that make sense?
