US Immigration from Mongolia

I'd like to go sightseeing in California or New York during my university holiday season this year or next year.
I identify as a "gay" student (22) and was wondering if telling the visa officer my true reason for traveling is a good idea.

If he/she turns out homophobic, will he/she automatically deny me a B2 tourist visa on the spot? Or do they adhere to some strict moral code that prevents them from discriminating against marginalized people?
The areas I mentioned are liberal, diverse, friendly, accepting, and inspiring. For years, I've wanted to visit their gay towns, the Golden Gate Bridge, Hollywood, and the Statue of Liberty.
I want to make him/her feel somewhat emotional so that he/she believes I have a valid reason for traveling.
Should I remain silent on LGBTQ issues in general? Is it a plus or a minus to reveal my sexual orientation?

Hello, I'm a 22-year-old gay Mongolian international student living in Japan. I'm having LDR with a 37-year-old American guy. I'll be graduating from university in 1.5 years. So I'll be liberated. We hadn't seen each other in over 2 years. As a result, I'm concerned that form I-129F will fail because we haven't met in a long time because of Covid. We're more than just friends. We discussed marriage and other topics. What should we do if we decide to get married? Traveling is difficult for me because I have a Mongolian passport. Developed countries don't issue visas to a citizen of 3rd world countries easily. I'd like to hear from anyone who has had an international same-sex marriage. How did the procedure go? How much time did it take? Do we have the same rights/benefits as conventional hetero couples? Thank you very much.

My parents entered the U.S. with immigrant visa, in October, what is the current timeline from the date entered to receive your permanent resident card? Is there a way to check status?

"This is the first step to obtaining a K-1 nonimmigrant visa for your fianc (e). The K-1 nonimmigrant visa is also known as a fianc (e) visa."

The above is directly from USCIS website, if this is the case then I think us K1 applicants are ok as per the way the EO is written (in that it applies only to immigrant visas). I'm no lawyer though LOL. But this is my understanding based on the classification of the K1 and the language in the EO. Hopefully we can get someone to confirm this.

Is anyone else currently filling out their DS 160? We have gotten through the entire application, we uploaded a picture, it was accepted, but now it will not let us progress to the review or sign options. The button for the next sections is grayed out. I saved it and reopened it a few times and still nothing. I also tried multiple browsers and the same thing happens each time. Anybody have any idea what is going on? Is it just a technical issue on the gov'ts end and we need to wait it out? Thanks!!
