Seeing this, I totally understand the 500k covid deaths in the US... All over the world, people social distancing, stop coming together in large groups, no parties for over a year. USA: Nah, we dont care, lets party... I dont care that its a special b-day, its just really irresponsible and a VERY bad sign to the population. As an influencer, you have the responsibility to influence your viewers to do the right thing. This is the exact opposite. Again, I totally get the 500k covid deaths, you really brought it up on yourselfs USA... No wonder you're a bananarepublic.
