I guess I’m an older fan, I’ve certainly been reading before Flashpoint and I don’t think DC hates me. I do still think the reboot had just as many missteps as steps in the right direction. But the single most (and really the only truly, from my perspective,) offensive part of the reboot has to be, for me the de-ageing of pretty much everyone to make nearly everyone under 30. This ageism is really, honestly pretty offensive. The pre-Flashpoint DCU had heroes that ranged from seniors to children and they all fit into place. Changing this has done a disservice to everyone who enjoys the comics. What sort of message are you trying to send? How does this even make sense culturally?
For a lack of a more elegant explanation; people are staying younger longer nowadays. Lots of people don’t even move out of their parents homes until their mid to late 20’s, 30 years ago this was uncommon and a sign of a shut in. People live longer and do much more during this time. My dad is in his 60’s and drives around on the biggest bike Harley makes. While I’m sure there have always been some guys in their 60’s who do this sort of thing I couldn’t imagine my grandparents doing this or even wanting to try doing that during that time in their lives.
