"Well adults can act annoying too!" Don't even start
I'm so annoyed when people say this. In every single conversation about why someone wouldn't want a child somewhere, the cinema, a wedding, an airplane, etc. there's always people saying "well adults act disruptive too!!!" It's just whataboutism and it's not even true in every scenario. For example for a wedding, you can choose to only invite people who can act civilized.
Also what do they expect to get out of this logic? "You're right, rude assholes exist, so babies crying while I walk down the aisle are okay"??? Does that genuinely make sense to anyone here?
