Uplifting someone so that they can be in the same position as the majority is not an indication of fragility in any way. Reservation is the government’s way of uplifting people who have been discriminated against in the past, reservation has nothing to do with a person’s physical or mental strength or their tolerance.
Women, who have faced discrimination in numerous sectors in the past, now get reservation of seats in some places. So to answer the asked question, no reservation of seats and jobs for women does not indicate they are fragile in any way. Reservation just intends to bring everyone on the plain surface to compete equally and give everyone equal opportunities.
