Politics in Linkedin

Kh
So I am going through my Linkedin and come across a post where someone who worked for Obama administration posted saying 8 years wonderful working experience   (Work related) and then said will miss the President 
So the comments section instead of congratulating someone on their job experience in a social media dedicated for work/job or ignoring the post, it went fully political. I am not saying Obama supporters or Trump supporters, both were equally arguing politics in someone's job related post. 
Would you post politics in Linkedin?
Do you think it is right whatever your political inclinations?
Do you think this makes other country people laugh at you especially in a site where people are coming in for professional networking?
