while they can share views they are not always correct and well supported

With social media the blind leading the blind has become even more common. People also tend to stay with people they agree with and that is even more true with social media. your feed becomes tailored to what you like. people have found that "For all the hope that comes from connecting with new people and new ideas, researchers have found that online behavior is dominated by “homophily”: a tendency to listen to and associate with people like yourself, and to exclude outsiders. Social networks are bad at helping you empathize with people unlike you, but good at surrounding you with those who share your outlook." So the idea that people can find new ideas on social media is generally false.

If I am reading your post right you are saying that a president can go on, lets say twitter, create a "law" like you can only post once a day as an example and it would be allowed? If that is what you are trying to say then that is not correct. Presidents cannot just "make a law" for the fun of it. There is a very long that potential laws have to go through to become a law. Social media is also a company so if they want to kick out a politician for his ideas they can, like they did with Trump.

Hi! how would being asked to vote be a plus for social media and democracy? You are underaged so you couldn't vote anyway which could create confusion on who can and cant vote.

This might not be good that they are because they are seeing such extreme views. in a study they found that "nearly two-thirds of respondents ages 15 to 35 had seen extremist messages within the past three months." if they are seeing such of the extreme then when both sides are wrong they are just pointing fingers at each other and there is no middle ground.

Social Media is not good for democracy because it is being used as a target against people to bring people apart. In an study Colin stretch fount that Russia-linked posts were “an insidious attempt to drive people apart,” Colin Stretch, the general counsel for Facebook who will appear at the hearings, said in his prepared remarks. He called the posts “deeply disturbing,” and noted they focused on race, religion, gun rights, and gay and transgender issues.
