Yes, Tony Stark is a rich white cis guy. Congratulations, you have basic visual/reading comprehension! But he ALSO is a victim of child abuse, has major depressive disorder and PTSD, is an alcoholic, and has suffered multiple times from people manipulating and then betraying him. Which makes him a victim in ways other than race or orientation.
In case y’all forgot, the two current fandom faves are ALSO white cis men. Steve and Bucky? Have 75% of the same characteristics as Tony. So when some Tony fans get together and decide to push back against the constant mischaracterization and blame placed on Tony, you countering with “there’s no need to defend a rich white cis guy” makes you sound stupid as fuck.
