Younger people who were born as EU citizens may have a point.
On the other hand, I was born in a UK that wasn't even in the EEC, let alone forcibly bestowing me with EU citizenship.
There is a difference though. The EU citizenship that you were given requires nothing from you. You have always been completely free to ignore it and never use it - if that's what you wished - same as with any other of the various rights that you'll have been given during your lifetime. Language such as 'forcibly bestowing' hardly seems appropriate in that situation.
On the other hand, forcibly removing EU citizenship from people does impact many people's lives in a real way - most obviously restricting where they are allowed to live, work and study. I'm guessing that you had no intention of moving to Europe, so that doesn't affect you, but for many people it's life-changing: For some, it'll destroy their dreams of working, studying or retiring in the place that they wished to. For others, it may prevent them from easily being able to see or their partners or members of their families - or even to remain living with their partners. For others (those already abroad), it may actually force them to leave their homes, and for those already studying abroad too, it may prevent them from remaining in the towns and countries that have become their homes. (All that depends of course on what settlement the UK Government actually comes to, regarding free movement).
I do find it somewhat concerning that, as far as I've been able to tell from your posts, you appear not to see any problem with destroying other people's lives in this way

(Apologies if I'm mistaken and that's not what you think, but that does seem to be the impression given by your posts).
