"People are like, 'Why do you have time for all of these strangers?' But that is my outside connection to the world. I genuinely love doing it. I always have. I enjoy talking to people and feeling like I know them and having this conversation," Teigen told Glamour magazine.
Teigen briefly abandoned Twitter after she received threats following a message she posted about gun control.
But she still has no intention of biting her tongue on issues she feels passionately about, reports femalefirst.co.uk.
"Our lives would be so much easier if we didn't dabble in politics at all, but I don't want that kind of life. For us, we are willing to take that risk, because we believe in it so passionately."
