We would not be ignoring them if they were not so...half-nomadic in everything. Like, they are actively gunning for the stuff which we do not want time and again - of course we'll snub them. It's not about them, it's about hereditary land ownership, patriarchy and other stuff which we took such pains to avoid - and have gotten good results out of doing so.
Like, this is the same as saying 'those guys totally have a valid concern because they are being ignored' while pointing at creationists or flat earthers. The only concerning thing is that those morons exist and have any say at anything at all, and them being ignored is entirely their fault because they are talking utter bullshit.
Stallions are not at the same tier of 'the fuck is wrong with you shut the fuck up you bag of nuts' as flat earthers, but the same principle - that they are being ignored because they deserve it for being morons, not because we are some sort of villains - applies.
Not every opinion deserves to be heard and catered to, some are just stupid and that's that. Stallions managed to consistently be A Voice Of Regressive Stupidity, which, considering all their heroes, is actually impressive...then again, Caesar was a hero and he fucked up Republic so that kinda happens.
Heroic stats make them good at achieving their goals, but do not give wisdom or perspective to choose said goals correctly.
