Claiming everybody that uses marijuana is irresponsible is not an argument, it is not insightful and it is not rational - it is bigoted nonsense presented in the complete absence of any supporting evidence. Maybe you should spend more time thinking out your statements and doing research and less time rolling on the floor.
Some 224 or so years ago I am pretty sure you would have been saying "responsible adults don't oppose the King of England"
Did I claim that? You'll have to show me.
