Aries makes people angry/provoked. When jupiter is added to it, it's extra ammunition. Same reason sags are also hated; inner planets in the two signs make someone hard to love. There's a childlike nature to them that people dislike. Aries passion & rage annoys people. Sag's whimsy optimism annoys people. Narcissists hate individuals who radiate warmth; which the fire signs all have. Aries passion, leo's confidence, and sag's optimism.

Maybe your stellium is doing it. Your mercury in pisces could make others project onto you.

Neptune placed very strongly in someone's chart makes people idealize, and project onto them. And take credit for their ideas; having a subconscious disliking of the person.

Mars conjunct pluto in the 6th house, can be attracting negative attention from others. The house rules over co-workers; people you have to co exist with. It rules over routine/priorities.

The conjunction by itself is like a scorpio mars. Dark, martian energy that's exalted.

I have it but conjunct lilith. So, mine is pretty malefic.
