What are you protesting against?

I didn't follow the thrust of the argument.

One obvious response, with recent news in mind, is "I'm protesting against the US treatment of foreigners in concentration camps." Or "war with Iran" or any number of things with actual protestors.

So, quoting the end "I leave with this question once more: What are you protesting against right now? And what do you need to embrace it? "

What does it mean to embrace concentration camps? Or to embrace war with Iran?

It's like there's a different definition of "protesting against" than what I understand.
