I keep one-line blocks unbraced when possible and my reasoning is definitely not to feel like a tough macho man. It's more like a mild form of OCD where any syntax that's not necessary just bothers me if I don't omit it.
Reductio ad absurdum: I assume your variable names are single-letter, your Python is indented only one space per block level and every C program is a one-liner? You should check out the Code Golf stackexchange; you'd do well.
Kidding aside, I can appreciate your feeling of OCD (I fight that urge too) but remember that most syntax is for humans, not machines. Using braces communicates intent to the reader; omitting them offers an opportunity to stumble.
Nah, humans go by indentation anyway. Just use whatever brace style you like, but make sure you have a linter / formatter that makes sure your indentation agrees with your braces.
