Yes

If a woman who had transitioned into a man tried to play in mes sport they would stand no chance so why should a man who has transitioned into a woman be able play in woman's sport and take away the little opportunity that women do get in the sport industry.

Defeats the purpose of women competing in their own leagues. Have to recognise biological advantages in sports

Yes they have every right to as alltrans people have the right to feel comfortable when playing their sport. There is no problem for trans people to play in the team the gender they identify as. As they will have the same hormones as their teammates. Let trans people play sports!

Biological men have bodies evolved from thousands of years of hunting and gathering. Out muscle, bone and heart are naturally stronger and more so with training. To compete against women is unfair to female athletes who work and train so hard, only to be thrashed by a man. The idea is disgraceful

Biological men have a biological advantage in sports, especially those involving strength, speed or endurance - this is the reason why sex categories were introduced into sports in the first place, and why all men's records in directly comparable sports are better than women's, eg sprints and long distance running, swimming, cycling etc. Allowing transgender women to compete against biological women is unfair and takes opportunities away from biological women - the two potential solutions I see are either the invention of a third category to accommodate for athletes who do not identify with their biological sex, or having all athletes who do not identify with their biological sex compete in the male category.

They biology of males are females are different and the sex changes don’t do anything to counter this thus giving an unfair advantage

Biological males or females do not train all their lives to compete against someone who has the opposite biological sex. Transgender women have an unfair advantage regardless of hormonal treatments. Across the board whether transgender male or transgender female, transgenders should not compete against biological males or females.

It is not fair for for transgender athletes to compete in the same competitions as others because they are built different and would take advantage from it.

Men and Women are biologically different, there is nothing wrong with being different from another.
However allowing athletes who are biologically different compete again the opposite sex is unfair to those who have dedicated their lives to their spot.
A separate category should be established solely for trans people.

Its just common sense not to have men competing against woman. How did this ever happen to be a thing?

It is a proven scientific fact that transgender athletes ( male to female) who undergo puberty have physical advantages over women. Therefore fair competition involving strength and or speed are impossible.

Males and females are biologically different, until we have years of research proving that transgender women do not have an advantage when competing against biological women, they should not be competing against each other. Funny how this is more of an issue for transgender women than for transgender men.

it's not fair for the biological women, they will have to train way harder to achieve worse results then the biological men

The science currently indicates that the impacts of testosterone on the human body are too great to be overcome by hormonal therapy for a duration of just 12-24 months. Therefore transgender athletes transitioning from male to female will have an advantage over biological female athletes.

For competitions in which physiology plays a significant role (e.g. physical strength), allowing trans athletes to compete without restriction removes any validity of gender-specific competition (such as women's categories in any sport), and even calls drug testing into question.

Biological males develop testosterone and develop muscle tissue and muscle memory and have an unfair advantage over biological females
