Not everyone will think your character is cool the way you do. Not everyone is going to like the ships you write or how you plot things. If a player and their character annoys you, chances are that a player will find you and the character(s) you're writing to be annoying too. It happens.
As long as you're not harming anyone write anyway. Write your character and your plots. Have fun. Don't be worried about annoying people. If they're being petty about you behind your back then let them, you can't stop them. If you're having fun and have writing partners that will engage with you, focus on that.
