Nowadays, we live in a world where people just say whatever they want and don't really care how it effects people. I think that Shimiras ha lashon(guarding speech) was made for this generation. When someone speaks very rudely about someone, who they think is silly or weird , that's sad. We shouldn't stoop to the level of making fun of people, or Unnecessarily criticizing someone. While we might think that 'so and so' is silly or weird, we should use discipline and self control.
Of course, sometimes we need to say something about someone if it is for a constructive purpose like protecting people, then you go talk to someone who can help fix the situation. Otherwise, talking rudely or making fun of someone is just wrong. We should remember that Lashon hara and hurtful words have consequences both physically and spiritually, where as shimiras halason brings blessing. We wonder where Moshiach is. It's up to us to help bring it closer with our effort of unity, we can each make a difference
