Thiest dont really have an issue with your lack of faith. Its more that its part of there religion to spread their faith. Therefore, they approach people (atheists) and talk with them about their faith and how they should also have faith. Some just are really aggressive and shove it down your throat while others dont do it so harshly. Depends on the person. But i hate when it get stereotyped so often. Just because one person is aggressive/disrespectful in sharing there faith somehow classifies all other people of that faith as aggressive and disrespectful. Thats the part that gets me upset.
