I was just kicked out of my band

So I was just fired from a band I just joined. The bassist was playing like it was a lead instrument, and me calling that stuff out definitely didn't go well. It was one of the first times I played with them. I'm a traditionalist, old-school kinda guy when it comes to bass, and this guy was doing chords, slapping, tapping in the songs we played. He had more pedals than me, the lead guitarist – and more STRINGS too, he brought a 7 string bass out a couple times.

I try not to judge, but I feel like all that stuff goes against what BASS means. And after getting a bit tired of him playing his melodies, and fancy licks I asked him to tone it down. I got put on the spot, so I put on some AC/DC to show him how bass is done, and he just rolls his eyes and looks at the drummer who starts chuckling. I put on some ZZ Top (ri.p Dusty Hill), then some Van Halen and he started chuckling. He said I "didn't have a good mindset" and flat out asked me to start packing my stuff at the end of rehearsal. Bummer, since they had a couple good paying gigs in the future.

Anybody have any experience with these "lead bassists"? To me, bass is bass, not treble – I may not play it, but I know it's made to get people moving, not make melodies. It's a RHYTHM INSTRUMENT after all, and this guy went all over the fretboard like a guitar player. Seems he was more YouTube bassist, or a Primus guy than a proper bassist.
