It's a Communistic tool. Communism needs to redefine words, in order to control Communism is based on lies, which is why it tries to redefine he as "she", and she as "he".
Those who try to impose different pronouns are really asking someone to speak a different and dishonest language (e.g. Communism, New-speak etc.), where the words used describe the opposite of what the definition is - e.g. war is peace, freedom is slavery, sodomy is "gay", good is "wicked" etc. Another example is "abortion". Abortion has come to be spoken of as a woman's "right", but since when has a woman had the right to murder a child? Another example is "piracy". Copying software or art has come to be known as "piracy", but since when has sharing involved plunder or deprivation of someone else's property?
