I go a few times a year for meetings.
As long as you have an ESTA, haven't told fibs to get it, no criminal record, accommodation for your stay, enough money and a legit reason for travel (tourism is legit), you're likely to be fine.
Being white does help, sadly, when it comes to getting pulled for 'random' screening.
When I tell them I'm there for meetings, they do sometimes ask a few more questions to see if I need a work visa, but what I'm there for is covered by the ESTA. Sometimes I just tell them I'm there for tourism, they rarely challenge that.
If you are unlucky enough to get pulled, and you've got a load of anti-US/Trump/Israel/whatever on your socials, good luck at the moment. Delete before travel.
I wouldn't recommend deleting social media apps from your phone either, especially if you're young. They'll be naturally suspicious and just search you up.
I travel with a large group of people, various nationalities and ethnicities, and while some of us have been pulled, none of us have been detained or turned away.
The only people I know that can get into the US are people who've lied about past criminality on an ESTA (which they don't investigate outside of very serious crimes), then declared said criminality on a visa application. That'll almost always get you a lifetime ban.
