To be clear, it doesn't actually matter if FNV got "retconned" by the show or not.
I'm already seeing people on social media post screenshots of Emil Pagliarulo's tweets where he confirms that FNV is canon to the show, but that was never what I was upset about. In fact, I didn't even notice until just now that the year that the "Fall of Shady Sands" happened the same year as the First Battle of Hoover Dam.
The thing is, even in the most generous interpretation: that FNV did happen, the writers just can't keep track of the year when it happened (an embarrassing mistake by itself) is still terrible, because that means that NCR and New Vegas got offscreened, and the events of FNV ended up not mattering worth a fuck. The way the writers handled this still speaks of immense disrespect towards Obsidian's work on the game.
making art is just like showering………can’t get up and do it, can’t stop when you’ve started. you want to crawl out of your skin if you don’t do it often enough. everything in the world is the exact same
the thing about when zionists ask you if "israel has a right to defend itself" is it's no different from someone asking "did you stop beating your wife yet" or the schoolyard bully asking "does your mom know you're gay". to answer yes OR no is to accept a false premise. asking if israel has the right to self defense is like asking if it has the right to time travel or the right to breed unicorns. in all three cases you're being asked about something that doesn't exist
if i break into your house and say it's mine now, and beat you up and lock you in a closet, do i have the right to "defend myself" against you fighting back? the answer is that nothing i do constitutes self-defense by definition. israel is the attacker, it is the invader, it is on the offensive, and anything it does to the palestinian people is part of that offensive. invaders always try to cry self-defense against the resistance to the invasion, but the only party in this situation whose actions can possibly be self-defense is palestine
