Do military recruiters check your facebook page?

[Bob]

I'm looking to join the Army but I have put up a few social media posts where I've been rather "critical" of the U.S. government, specifically the military's past deeds.
I'm patriotic but when something is wrong, the flag that's backing it up doesn't make it right.. So I've voiced that opinion a couple of times and am now wondering if it will effect my ability to serve.
I expressed interest in Special Forces and he said I'd be a good SF candidate. That athletes have an easier time in there. I didn't have the nerve to tell him about my FB posts when he told me I'd need clearance lol.
Can anyone help? Should I just delete my Facebook account?
