Lol, well, Saggitarius and Aries are both supposed to be highly chaotic and impulsive, so this much influence would be expected to make a difference, as well as venus in first house position being particularly associated with an easy going, self-indulgent quality in relationships. That part of the chart is really meant to be more about personal interaction style than anything deeper. Some of the astrological systems actually give more weight to the position of the moon (because it's associated with emotions) than even the sun, and multiple planets in the same sign (particularly in conjunction with each other, which is supposed to increase the harmonic energy) are going to give that sign a lot of overall influence in the chart.
Really, we can't even form a good basis for a critique of the system by looking at aspects in isolation due to their potential to be influenced by other aspects. This makes criticism by those who haven't really bothered trying to understand it in detail and are taking issue with specific single aspects rather weak. Maybe it doesn't work, but we still need to be able to make an appropriately nuanced qualitative assessment of how all the different variables integrate with each other.
I'll try some more specific Virgo rising sign traits anyway, just to see how many apply. Most of them should be present to some significant degree despite the strong influence of the other signs; though obviously we need to watch out for confirmation bias and the blah, blah effect here in trying to determine whether you have them to a notable degree:
Are you a "helper" or "carer" who likes to do a lot of things for others and is maybe particularly attracted to those who need that help? With regard to the ascendant position and the supposed virgo desire to be of practical service to people, do you tend to employ whatever organisational skills you have in order to help or support others, rather than yourself? Do you use your reason and ability to detach emotionally and focus on practical necessities, enabling you to remain fairly easygoing and flexible in most situations? Do you have a very keen awareness of your own body (more so than most people) and tend to worry a lot about minor ailments, perhaps blowing them out of proportion? Is health, nutrition and exercise generally a big deal for you, other people's as well as your own? Are you a worrier in general, particularly when it comes to thinking about what might go wrong in your social interactions and relationships? In this context in particular, do you notice a lot of details that others are not likely to pick up on? Oh, and where is the position of Mercury? This is also supposed to affect Virgo strongly due to being the ruling planet.
