Is profanity essentially gender-biased?

Some years ago I came across a feminist argument about profanity. It proposes that profane words and phrases are related to feminine attributes, only because the society and the masculine counterparts in particular, regard female as subhuman or less-than-man, at least. Suppose ‘motherfucker’ is a profane expression because it has something to do with feminine weakness.

I was more or less convinced and later it slipped out of my mind.

Many days later the argument prompted again and this time I was not convinced anymore. I think an expression can be profane when it has some sort of sensitivity regardless of its gender inclination.

It has SENSITIVITY at its core and nothing else.

Profanity is not essentially gender oriented practice. Let’s put forward some examples (both from West and East) and examine them.

1) Motherf×××
2) Pubic hair (baal in Bengali)
3) Holy Shit
4) Jesus Fu××× Christ

It is always Motherf××× and never Grandmotherf×××. It is profane because the relation between mother and son is more sensitive than that of grandson and grandmother.

Pubic hair is gender neutral.

Shit is never holy. The association between holiness and shit makes it sensitive and therefore profane.

Christ is never fu××× either. Sensitivity is very clear here, gender neutrality also.

The argument seems baseless now.
