Is it normal to believe that "gender equality" is unrealistic and fallacious?

You're attacking a strawman.

The idea of equality is that the institutions of society treat people the same regardless of their gender and provide the same opportunities to each gender. This allows people to be free to follow their individual preferences, to have freedom in other words.

Gender equality never included the idea that men could give birth or that women have on average the physical strength of men. That would be ridiculous and virtually no one believes that. While I have big problems with the feminist movement, I have no issue with gender equality. It's basically the same cause as freedom and removing it will decrease the freedom of both genders to make choices.

Just because our needs are not the same dos not mean we cannot give equal opportunity to have those needs met.

Why is this concept lost on so many?

Gender equality is having the same social, political, legal and human rights regardless of gender.

It is not that men and women are the same.

The word fallacious makes me think of blow jobs.

As a sociologist, I'd like to point out how inaccurate your arguments are. First off, this is a strawman fallacy. This is not the desire of feminism. The feminist goal, though varied based on schools of thought, is to have men and women have equal opportunity and be held to the same standards of action, without judgement based on socially enforced assumptions and roles.
Women, though physically different, vary little to none in functional levels as compared to men. This of course excludes the physical difference that would make some professionalism difficult for the majority of the members of the sexes like contortionism for men, or construction work for women.
As for gender,-yes, it's different; do the research yourself- it's only socially enforced as it is marked by the behaviors we expect from the sexes and the roles we attribute to those behaviors. The ideas of masculinity and femininity come from these concepts. Some cultures have other genders because they have constructed the roles differently, leaving some cultures with three, four, or even five genders.
Most of the inequality comes from discrimination based on gender and not sex, which is why "gender equality" is such an issue. It's caused because people assume that just because someone has a vagina, they aren't emotionally capable of being a CEO or running a country. It's the assumption that because someone has testicles, they aren't suitable to care for children or it is inappropriate for them to be a midwife.
That's the basics... for the most part. It DOES get more complicated than this.

Speaking in general, women and men do not think the same. But you have cases of very masculine women and very feminine men, so I disagree with you.

For example, going through high school, I had a friend named Jordan. Yes, he was guy, but he was still a man. Everything about him was feminine and when I talked to him, I felt like I was talking to another female.

There was also a girl named Autumn, I knew. This girl was just like a dude. Sometimes, I forgot she was even female. She looked like a dude, talked like a dude, walkied like a dude and, when you'd first meet her, you'd think that she was a dude. She did not carry a single feminine bone in her body. But, never the less, she was still female.

Everybodies different. I will not deny that the majority of males act a certain way and a majority of females act a certain way, but to take everyone there is and put them into a group, I'll have to disagree with. I've seen too many different people all with their own personalities. You have some more feminine people and some more masculine people, and gender doesn't always play a role in that.

I have no issues at all with equality, my wife is the breadwinner at present, while I am completing my honours degree. She is in the catering business, so theoretically she is still in the kitchen....problem sorted.

Where's Itduz?

I'm a woman and I happen to completely agree with this. This gender equality is for the birds. Women and men are not equal. Men can't give birth and women can't write their names in the snow. Plain and simple. They both carry their own importances.

Yes

IN the sense that you're phrasing this question, I'll agree with your conclusion. A lot of how men and women act in today's society is simply societal construct, but there are still biological and psychological differences between male and female that cannot be equated.

without the ability to dispense sex women would be utterly useless for the most part
