Depends what you mean by golf. Finding a morning to play 2 holes a short helicopter hop away is playing golf. But it's not fly to Mar A Lago and ignore all responsibility level of playing golf.
He played like 350 rounds of golf during his presidency. That seems fine to me, but it seems weird to try to minimize that fact. He would regularly fly and play at resorts in Florida, Martha's Vineyard, and around DC. I Googled it, it was pretty well covered.
If that seems problematic to you, think about this: Trump (among many others) loudly criticized Obama for how much golf he played, but then when Trump took office, he proceeded to play twice as much golf.
If you think that's crazy, Woodrow Wilson played twice as much as Trump!! Even during WWI!
I'm weirdly attached to fighting stupid conservative propaganda. Let's put it a third way. Trump golfed about every 3.4 days, while Obama golfed about every 8.8 days.
It's a sport where you can walk, talk, and do a sport. Decent way to get very moderate exercise while also doing work. I can see why it's popular. My guess is most presidents (except Trump) who golf do so to get outside for a bit in a secluded area while working given the job is nonstop.
