You saying "Go listen to amazing music, go out and see the nature, or go to a party that fits with the acid trip." isn't stating an opinion. Using "I think" or "I feel" instead of "Go" is the way to go about stating an opinion.
Maybe you can understand my frustration when someone like yourself comes along and says they're stating an opinion, but doesn't write it as an actual opinion, and tries to defend what they wrote that was meant to be an opinion, when they should have payed more attention in English class on how to start a sentence. But that's just me and the way I feel, maybe you did have the intention of stating your opinion about it.
