I'm of the same Uranus in Gemini generation as yourself and I have noticed that it's this age group that first seriously explored independent thought, and got into the alternative thinking sectors and, literally, saw things in different ways. We are not argumentative but have out-of-the-ordinary ideas that are considered 'way out' by our peers or 'cranky' by our children. You have Uranus in the Aquarius decanate of Gemini, which could make you especially highly strung or rather nervy, yet very intuitive regarding what is going on directly around you. Add a Sag. Sun with its thirst for knowledge, knowing what's going on, and passing on what it believes to be true, and you may come across as a sort of oracle to the less initiated who are not interested in hearing/listening to your specialised brand of wisdom because it is not their own.
With tr. Mars in Gemini, disagreements of opinions and ideas are generally more highlighted than at other times, and with a conjunction to Uranus and opposition to Sun, things could become extremely intensified whilst the aspect is in orb. You could literally blow a socket or be the receiver from one who blows theirs!
I was unable to get your chart image but, from what you wrote, it sounds as if you may also have a strong water and/or Neptune element that makes you very sensitive to your environment. A problem with water is that it gets into and envelops every nook and cranny ....also of people. It takes up all the free space, leaving it difficult for the people concerned to find and inhabit theirs independently. Sometimes the water must recede to allow people a breathing space to do their own thing.
Transiting Pluto to Sun means a complete change from an old way of life that has outlived its purpose, to a totally new experience of life that is the next step. The transition needs time to get used to, so the change is gradual and spread over a number of years so that, by the time it has happened, it isn't as scarey as one might have anticipated it to be. The house in which the natal Sun is placed is the realm that undergoes the transition and one evolves as a completely different person within it.
Maybe you are in the process of changing, not to convince or be like other people, but to be true to yourself?
