라던지 and 라든지 mean the same thing, 하길바라 is grammatically incorrect.....하길바래 isn't. 하길 바란다 or 하길 바라고있어 makes sense, 하길바라 doesn't.

in the context of your sentence I'm thinking it means 'meaningless' or 'insignificant'.

"if only" implies a wish/desire. you want something. "only if" indicates a necessary condition be fulfilled. like "not unless".

your last sentence sounds the most likely, but you're leaving out '해'. it would be 시간이 있을 때 얘기해도 돼요? 시간 있으실때 얘기할까요? or 시간 있으실때 얘기 할수 있을까요? might sound more natural.

공감 means empathizing or feeling the same.

The problem doesn't lie with Korean media, it's the people who fetishize Korea and Koreans who are the source of the problem. The responsibilty and onus lies with non-Koreans to not be racist and fetishize, not on Koreans, whether they are represented accurately or inaccurately by Korean media. Korean people are not a monolith.
