The word comes into being because some people may hide their sexual orientation or refuse to admit that they are gay because of social pressure and traditional ideas. Therefore, when one party expresses affection for the other party, the other party may respond by saying "no" to cover up its true thoughts or feelings.
It should be noted that the word "speaking out against" does not represent all situations in gay relationships. Everyone's emotions and sexual orientation are independent and cannot be summarized or summarized in simple words.
