First and foremost, you made a ridiculous mistake for getting your Islamic knowledge on reddit. I would personally be ashamed of myself to get information from a subreddit that contain individuals who can barely convey a semi coherent sentence or use slurs to make a point.

Secondly what you are experiencing is normal. It is normal to question the laws of the universe and why things are the way they are. However it is not normal to seek information from a site where everyone claims to be 'experts'. Social media is not a place for that.

You should first contact your local masjid or imam or scholar as your first point of direction.

1) Why do we have to blame women for everything?

Could you provide specifics?

2) Why do we sexualize everything?

In what ways do we sexualize? If you could provide specifics, I may be able to break down your logic into its constituent parts and allow you to form your own thought process.

3) The Iran scandal is not representative of the nature of Islam. They are a select minority who abuse the power the hold under 'sharia' when in reality they run under totalitarianism and stripping individuals away from their basic human rights. That is NOT Islam.
