Ah the fine line on social media between being yourself and not making everyone else uncomfortable. It's a moving target, invisible at worst and moving at best. You can do what you can to control who sees your posts by double-checking those privacy settings and using care with political, religious and sexual comments. An ill-advised joke or offhand comment could tag you with an unintended and unfair bias if seen by the wrong person.
Consider who might potentially see your words. Before you click "post," think about your boss, your co-workers and the next company for which you hope to work. By exercising a little common sense, you can build your case rather than sabotage your chances.
