To know the legal situation about LGBT+ people in your specific country, the internet is a great resource. However, if you live in a country that monitors media access or restricts the media in any form then it might be best to go to a library or an institute that holds legal records or legal information of any kind and start your research there.

The absolutely best resource is Equaldex (equaldex.com), which gathers info on the legal situation of the LGBT+ folk around the world.

Google can probably answer some of your questions! But, laws can be hard to read at times. In an English-speaking country I'd look for laws that use words like "sodomy", see if "marriage is between one man and one woman" and search if "sexual orientation" is protect in civil right ordinances/laws. I'd also look for "religious freedom" laws that allow for discrimination based in religious beliefs. Based on an American perspective, those things might lead you to answers. If possible, check in with a local LGBTQ+ community and find out the legal situation of LGBTQ+ people in your area.
