Propositions; statements that are either "true" or "false".

You don't know what "p" and "q" stand for? Those are incredibly common variables representing propositions in symbolic logic--like "x" represents a number in mathematics.
Do you know basic logic?
Is the statement "1+1=3 implies Barack Obama is president" true, where "implies" refers to material implication?

Pot, meet kettle.
Uh, what? This place characterizes itself as a place of logic and reason. It isn't 'lumping everyone together' to think that people here will know basic logic. I'm just surprised that some people here are actively hostile toward symbolic logic.
