Does this mean that any company that targets an ad to men / women only on social media platforms can be sued for discrimination?

No, there are a bunch of areas that have specific laws prohibiting gender discrimination. Employment is one of them, housing and credit also have similar laws, but not most consumer goods and services.

No, this is specific to employment law. You can advertise products or services to whomever you wish. Employment must have equal opportunity.

I mistyped. I meant targets a gender for employment.
