@Emil12345558 It's not just that Aizen said he wouldn't turn himself into a hollow and abused the Vizards, no Shinigami apart from Tosen has shown the slightest bit of affinity towards hollows. Even the Vizards have shown nothing by disdain towards hollows. Only reason Tosen wanted to become more like a hollow is because he hated Shinigami.

So it's not just a matter of Aizen saying "I am not a hollow", the psychological profile of most Shinigami say that they aren't particularly fond of Hollows and would generally, never choose to become hollow-like if they could at all help it. This is true of all the Vizards and Ichigo, none of them chose to become part-hollow. More importantly, clearly, Aizen COULD help it and gain more power then a Shinigami is allowed by using the Hōgyoku

There may be a lot of Hollow sympathisers in the Bleach fandom but only real Hollow sympathiser in the Bleach universe is Tosen. Everybody else... well since Arrancar can reason, they generally threat them as sentient beings but apart from that, most Bleach characters wouldn't distinguish between a Hollow and a rabid animal. Would you want to have rabies?
