You seem to be fixating on the term "fight back," when the commenter you're replying to is asking for ways to not feel excluded at his/her job, where s/he spends a majority of his/her waking hours.
As someone who has experienced this, I encourage you to draw on that experience and have empathy, even if that experience is expressed in ways that don't immediately resonate with you. You have more in common with the commenter you're replying to than you appreciate.

And the people GP is talking about are trying to do the exact same thing, though obviously in highly detrimental ways. Part of professionalism entails not making your job into an identity that overwhelms every other aspect of your life. If you just focus on delivering good results to the best of your ability, there's no need to be dependent on constant social approval from 'insider' peers.
this is fascinating to me because it’s how i have handled my career and it’s had unexpected positive and negative effects. all-in-all i’m more satisfied than my friend group with my day to day work existence but am steps behind them in the traditional career path milestones. though i lack the titles they have, i’m squarely median when it comes to annual base income, which is comfortable and provides very well for my family. however, i’m beginning to age and realize that potential employers are beginning to balk at my title/“informal” leadership (read “experience”) with my age and salary and duration in the workforce.
