When you point out that others did the same thing you're doing now in the past, it means you didn't like it in the past and have no issue with the behavior now.
Hey mate,
Hope you're having a decent day.
I've been thinking a bit about your posts lately, and something's been on my mind. It seems like you may got some really solid points you're trying to make, but all the insults and sharp words are sort of getting in the way. It’s a bit like trying to win a fancy dress competition by insulting the judges' outfits—you might have the best costume, but nobody’s going to notice!
I reckon you've got a lot of passion for what you believe in, and that's brilliant. But all the a bit of harshness just ends up undermining your own case. People get so focused on the jabs that they miss the actual substance of what you’re saying, provided there's any, which is a real shame.
Anyway, just a thought. Maybe give it a go and see what happens? Either way, keep up the fight, just maybe with a bit less of the verbal sparring.
Cheers.
