Did you know?

Proponent comes from the same Latin word as propose, so a proponent is someone who proposes something, or at least supports it by speaking and writing in favor of it. Thus, for example, proponents of casinos argue that they create jobs, whereas proponents of a casino ban—that is, casino opponents—argue that they're corrupting and they take money away from people who can't afford it. As a rule, just about anything important that gets proposed also gets opposed.
