I've been thinking about this for a while, and it makes sense to me. I've asked about it before, and some seem to agree while others aren't even sure that ascendant aspects other than the conjunctions matter at all. One site I've come across doesn't even offer descriptions for any trines or squares or anything to the ascendant other than the conjunctions.
Do the different ascendants give each aspect to it a specific ascendant ruler quality? For instance, would a Mercury square Pisces ascendant be similar to a Mercury square Neptune (or Jupiter, if you want to use ancient rulers)? Would a Mercury trine to Gemini/Virgo ascendant be like Mercury trine Mercury? Is that even a thing? Is that where my theory falters, or could it still apply? I'd like some other opinions on this.
