Put,
It’s not Titus menorah, rather it is practically almost every archaeological finding, points out to be round branches. Let it be in Caro geniza, coins, 2000 year old shuls in Tiveria, Tzipori, Jerusalem, all mosaic drawings and cavings are round. and is thus consistent with how all Klal Yisrael has known it.
I understand there are some other shitos, but deciding so based on one pshat (which can very well be debated – refer to my last link I posted) against overwhelming evidence that keeps on piling up, is absurd.
Especially if that is against how all have known it.
