So do you want 5 year olds driving on the highway and 8 year olds doing shots of tequila or are you ageist?
Or perhaps protecting kids isn’t really ageism at all.
If the 5-year-old has passed a proper driving test, why not?
It depends on what you're depriving them of too. Those are very extreme examples with little to no upside.
Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize.[1]
