What are the main possible reasons why some people oppose LGBTIQA rights and same-sex marriage?

Apart from the usual scapegoat that fundamental religious beliefs are the main reasons why some people oppose LGBTQAI rights and same-sex marriage, what are the possible reasons why people oppose these things despite scientific research saying that it is not exactly unnatural to develop that kind of "different" sexuality?

I heard that some people are afraid of change because of the fear of the unknown or the fear that the change will be done by force and the heterosexuals became dominated and the new minority *(same way people were afraid when African-Americans demanded equal rights or when Communism was rising in power and influence)*

I also heard that people neglect whatever the demand on equal rights claim because they claim that it is dominated by teenagers and young adults because they are being rebellious and illogical *(which is kinda true in a sense because it has been considered a usual part of development for many teenagers and young adults to go through risk-taking and rebellious behaviours but not all of them do)*

It's hard to get away from the religious aspect, though, especially because these oppositions were not the norm until quite recently.

For example, the recent book *Gay Indians in Brazil: Untold Stories of the Colonization of Indian Sexualities* shows that, at least in the case of pre-Columbian Brazil, non-cis-straight behaviour was not persecuted by the native population, and homophobia and transphobia were European (Catholic) impositions.

The same appears to be true of Japan before European contact, although the situation there was a bit different, with their hierarchical and patriarchal social structure being more accepting of gay and bisexual men than of women (highly recommend the book *Manga Girl Seeks Herbivore Boy: Studying Japanese Gender at Cambridge* on this subject).

So yeah, Judaism/Christianity/Islam seem to be intrinsically connected with why the *current* world has anti-LGBTQ+ movements, so even if people are not practicing Jews/Christians/Muslims, they can still enforce these (religion-based) social mores that are embedded in their social millieu.
