、。
Well, broadly speaking, it's not wrong.
Literal
Well, broad-sense-ly [as-for-には], not-wrong [polite-ません] [confirmation-ね].
広義的に (or 広義的には) is a formal adverbial phrase meaning 'broadly speaking / in a broad sense,' where 広義 ('broad meaning') + 的 turns a noun into an adjectival/adverbial modifier — a productive formal device. The contrast particle には (に + は) scopes the adverbial as 'when it comes to [broadness],' hedging the agreement. Sentence-final ね invites confirmation.
