It’s absurd in every country you visit as they all have the right to deny you entry, regardless of agreements or visas. But, you still buy that return ticket.
Thailand is no different. They aren’t obliged to give you the 60 day visa exemption, they aren’t obliged to allow entry. So, it’s the same every time you travel.
No. I’m happy to criticise anyone, regardless of gender or race. You failed to answer the question so I commented on your post. If you think being a woman gives you immunity, then you’re wrong.
