I believe things largely depend on/need to be appropriately seen in regards to specific context, and also (as u/dignityanddomicile has stated, that this may be read as a natural part of human life and of growing up. Maybe libra personalities are more in the spotlight sometimes too, so people just notice their specific traits/developments a bit more. Growth involves stages of development. But don't forget that one's development is dependent on context, too (not just sun sign), although you may feel it is an uncanny coincidence, these parallels you are drawing from libras you know personally. As a lifetime student of human behavior and anthropological phenomenon, and astrology too, it would be interesting to know additional specifics related to age, location, 'group' category too of the people you are referencing. Perhaps it is because libra is in my 12th house (which has taken me on my path of spirituality and of service to others)....but no, this is not typical libra thing. Thinking about my more outgoing libra friends, they have always been the sweetest, funniest people just aiming to enjoy life and to find comfort through peaceful (and also many community) initiatives with their world outside. People have asked me my whole life how I have been calm and non-aggressive and forgiving, and how I didn't 'blow up' after certain known situations with others who have been less-than-acceptable in behavior and actions. Also, I have my own practices (specifically yoga, and meditation but in general...exercise, gardening, reading, art, music) that assist me in handling these energies from other people so as to not adopt them myself, so that helps. As with anything, find something to do as an 'outlet' for when the world isn't always peaceful, so that you can find peace within. Libra is a peacekeeper. A lot of internal work in my life has been done to keep peace as message and ideal that I believe in. It's good work.
