is this too nerdy?

my father is absolutely against me buying an own army as he sees this hobby as "too nerdy", is he right?

UPDATE: my mother is compliant so i do not need to go behind their back, and im gonna shit a little on the oppinion of my dad (sorry if your reading this btw), maybe i can attend my first tournament in february , love yall

UPDATE: I have the money for the army, its a 7th edition khorne legion for 150 bucks round about 1.5k points, should i buy it (important)
