These natural traits can be shaped outside and in life. A crossdressing male if brought up in a more male strict and/or dominated household with male dominated distractions may submerge and cover up any proclivity towards a genetic trait where said male would wish to crossdress... Out of sight, out of mind. This natural genetic trait may just be buried deep under other traits and life's baggage. These males may use things like Halloween or say a costume party to indulge a latent crossdressing trait. This may be enough for many cders. Others will compensate by fantasy, dressing only in their minds often with masturbation. Still others this buried trait may only lead to a general malaise and depression if not allowed to come out and be a part off this otherwise regular male . This could lead to abusive marriages, parenting and the use of booze and drugs to temporarily stunt these feelings.
Girls who are not too girly were for generations seen as tomboys and accepted as such by society. The struggle for a female to be more tomboyish and 'butch' is not as bad as for a boy to be seen as effeminate... MALE PRIVILEGE MY backside!!!
Some of these cders may take on daring or dangerous activities and jobs to help fight these underlying traits. "What? I don't like to wear women's clothes, look what I do for a living, I'm a demolitions expert or a soldier, a race car driver, a cop, a fire fighter etc. I'm not saying males in said jobs/activities are all closeted cders, but for some who fought this trait since their earliest years it's away of over compensating.
IMO many males who are very negative towards trans persons, cders and even gays they do such to try to not to show their own proclivity of traits to the alternative life style.
Many women who are transphobic, anti-cder or homophobic are often from very conservative homes and fear the unknown of a man they may be involved with being a cder or they may not like that many trans women are often seen as more feminine and attractive than many genetic girls. These trans women are walking on their turf so to speak, or they too are closeted lesbians and hate that fact some respond badly towards LGBT persons.
As to transgender persons, pretty well all I see, hear and read about have felt they are in the wrong body since childhood. Gender dysphoria is a real thing. Many go without help and hide behind 'normalcy expectations' by family, friends, community and life. Many live confused and angry as a result they suffer a deep depression out of it all. A healthy society does not block, fight or abuse transgender persons. Transgender persons want to CROSS to the GENDER they believe they should have been born as, MTF or FTM... It's that simple. So our society has the ability to now help trans gender persons find their way. Support from family, friends, school or employment and in medicine helps these people find their place. Suicide rates of trans persons denied their path or not having such support when going down said path is many times higher than the normal reference rate of society's suicide rates. BUT! with proper family support, community support and medical support, trans gender persons see a suicide rate fall right back to societal norms
Nobody has to like, YOU, ME any of US for any reasons... Society needs to get over imposing likability to others. I want the haters in the world (BTW ALL PEOPLE CAN HATE AT TIMES IN LIFE! To say otherwise is a lie.) to be open to hate, it only shows them for their ignorance and pigheadedness even lack of self confidence. It allows us to see, deal, debate, inform or avoid them. Shutting up hate does no eliminate it, it only makes it worse and that will see some strike out from the shadows.
Stop only those persons who instigate violence and/or panic. Shine the light of life on haters who have no real position to stand on. I do not want to walk around a corner in a dress and heels only to have an angry hater lash out from the shadows to attack me. Let haters verbally hang on their own noose of life. Maybe, just maybe some can be talked to and see that me as a cder or another person as a tger are just regular people finding our ways through life and mean no harm.
