If you're trying to assist potential new joiners in having a better (more balanced) perspective, then be balanced.
You say that rosters improve over time; they may for an FO but they don't for a DEC. That's not balanced.
You say that it's fun flying to places like Juba, Kabul etc.... many people may disagree with you. That's not balanced. In fact, I would go further and say that some of our destinations are extremely unsafe.
No one suggested that you have to whinge, you just need to be a bit more candid when supplying info to potential new joiners, which you weren't.
And no, I'm not the opinion police, but if you post a comment you shouldn't be offended when someone disagrees with you.
