My first year doing this gig, I received a lot of criticism for some of the content in my first and second SF novels. More than one concerned SF writer tried to save my career by explaining to me how SF was supposed to be written.
Here's the killer: the sex was fine with them, as long as I cleaned it up and used more of a softer, more distant focus with the presentation. The problem was the romance subplots that they predicted would ruin me as a SF writer.
Romance -- the love story between two characters -- had no business being in a SF novel.
Looking back now, some of what was said and done to me seems unforgivable. I cannot believe these people did this to a rookie; you never, never mess with a newly-published writer that way. But even in my first pro year, I was contrary. I believe that love, sex, and romance are an important part of life. As a writer, I'm not going to hide them under the story carpet. Also (important tip) it's a mistake to tell me what I can and cannot write.
Six years and eight SF novels later, I'm still here. Still writing my SF novels with plenty of icky romance subplots in them. And yeah, I'm still hitting the SF mass market bestseller list every year.
This did not come without a price tag. Go against the flow, and you will get blackballed, ridiculed, sneered over, pointed at and otherwise censored -- and not just by other writers. Although my sales are terrific, you won't ever read about my books in most of the industry trades. The minute a SF writer gets on a national BSL list it's reported, but try to find a mention of me doing it. My books, which rack up pretty decent numbers, are not listed with the other new releases in SF. They're also not reviewed (but hey, I like that part.)
I am not a role model. Please make note of this.
The point is, if you're going to stand up for what you believe is right, and act on it, be prepared for the long-term cost to you. The herd does not thank you for leaving them. Even if you bond with other loners, there are always more of herd than there are of you. It is in the herd's best interests to ignore you, and/or to do what they can to assure that you are not a success.
