It’s like saying “I’m not political”, it’s also a political statement/stance.
Personally I came up with my own flavour of practical Taoism as ideology; something like Konrad from the bridge trilogy
Personally, I think it's dogma that belongs in the bin, rather than ideology.
I can't really say it's based on anything empirical, but to me, ideology is almost meant to be critically analyzed where as dogma is based on strict acceptance.
I'd summarize my feelings by saying ideology is presented whereas dogma is dictated, if that makes any sense.
Dogma is what you follow blindly and don’t question, whereas ideology while still rigid you can examine and shape according to your own personal values.
