Strength isn't a big criteria for the job. If I need herculean strength to do a job, I find another way to do it. That's why we have lifts, rachet straps, clamps, etc. Work smart, not necessarily harder. If you're having to use a lot of strength, there's probably a better way you can be doing the job.
I don't care which restroom a co-worker uses. Male, female...who cares? I do care about competence and taking the job seriously. My respect goes to those who seek craftsmanship in their work, don't cut corners, and take seriously the tasks to which they sign their name. I treat a female the same on the shop floor or in the cockpit.
