It’s a little wild to tell someone they should spend this energy doing something about it instead of writing

That’s not what freagle said though. The argument wasn’t that jjj shouldn’t write or that they shouldn’t try to influence people, the argument was that they shouldn’t be wasting their time and energy trying to influence people to vote because voting is ultimately useless. Freagle never said that trying to influence people period is a waste. So no, what they said did not ring hollow and there was no hypocrisy in writing a long a comment explaining why it is a waste to try to get people to vote or to vote a certain way.

You either didn’t understand or deliberately mischaracterized what freagle was actually saying so you can’t claim it was just constructive criticism.
