No, nobody can be fired for whatever gender, sexual orientation, religion or beliefs they have. The focus on LGBTQ+ or certain religious beliefs is due to the media focus and because of the countless instances where such terminations, both legal or illegally, have taken place. These legislations give these groups the same rights everybody else already enjoys, and are usually formulated in such a way that any discrimination in regards to gender, etc. are forbidden, this includes white, straight cis-men.
