I would have used a comma before the final "and" or "or" in a series, like this:
mother, and lesbian
church, or community
You need "losing parental custody" -- one "o" in "losing".
I think you need a more parallel structure than "as an activist and through faith", maybe "through faith and activism" or "through activism and faith".
The choice of "accompany" in "... injustices that accompany many gays ..." is not really satisfactory. I'm not sure that injustices can "accompany" people -- maybe "face", "confront", "are experienced by", something like that?
I would have used "discrimination" rather than "discriminations".
"the key in building bridges" should be "the key to building bridges". (We say "the key to the locker", right? -- not "the key in the locker"!) But, on the other hand, you may want to reconsider whether you really want to say what you said in the final sentence. How is your reader going to interpret "building bridges between the gender issues"? In what sense is there a bridge between one gender issue and another gender issue? I can't be sure, but I think you intend to say something a little different from what you actually wrote.
You may want to consider using "Boatwright" less often or at least using it in a greater variety of positions within the sentences. It is the first word in a large number of the sentences in the essay. Likewise, the word "Colorado" comes up too close to another "Colorado", and the same happens with "church" in another passage.
Related to that, you could provide the reader with a little more interest if you were to use a greater variety of sentence structures. For example, you might use a few more subordinate clauses with "although", "since", "because", and so on. Varying the length of the sentences might also help. And your reader would be swept along through the essay more smoothly, I think, if you used just a little sprinkling of some connective expressions to relate sentences to one another -- like "yet", "still", "nevertheless", "also", "further", "even so", and so on -- but you don't want to overdo it, and you'll need to think of what will work best with the meanings of the sentences.
Writing is extremely difficult; you've done a great job, and my suggestions are mostly to do with polishing what you have so far. I hope they will help.
