I personally would not say, "tremendous disrespect",because I don't know what's in the hearts and minds of others, however, I do agree the Sidereal is the way to go, because of the keeping to the Astronomical data, the backdrop of the stars and constellations. I don't know if it's laziness or just habit of the Astrologers, but whatever it is, it's their own path.
To each their own, I always say. I'll read anything in a given topic, if it's decent Astrology based. (given the time I have available to me in a given week or day.
You're right. I should have said "ABSOLUTE disregard" of Vedic astrology when it comes down to when the Aquarian Age will formally begin, using the Vernal Equinoctial Point (VP), at the time the VP first ingresses sidereal Aquarius.
