Only if you don’t bother to learn what the words you use mean.

Inherited from Middle English con-, from Latin con-, from cum (“with”). … Indicating a common origin, from, coming from the root: consequence as what comes from the sequence

lol what?

‘con’ (in "pro(s) and “con(s)”) is for ‘contra.’ From the OED:

An argument or consideration in favour of something; reasoning in support of a proposition, thesis, etc. Chiefly in pros and cons (also pros and contras): reasons or arguments for and against something, advantages and disadvantages. Occas. also pro and contra (also pro and con): argument, debate.

Con is obviously shortened in modern usage, because it better matched “pro”.

“Con” means “against” and has nothing to do with “with” (or Latin “cum”).
