Holocaust: Tears

Hello everybody... The question was that if you were to converse with someone about the Holocaust and the person said that they did not believe in the Holocaust, that the holocaust was just some fake thing people made up..... I am a boy growing up but of truth... I feel like this..... In the inside..... When i think about what those  things and people went through..... It would put me in tears.... I don't think I could even talk anymore.... The reason is because the information and things that those people give you..... It is really intense..... There is even proof of those places..... At the same time on the outside I also respect other peoples opinion..... Respecting other peoples opinion will keep you from arguing or further conflict... So if someone told me that they felt like the Holocaust was just fake and it did not happen.... I would just say.... o ok.... But as a result of saying this.... It still does not change the way that I feel..... It is just out of respect.... And also to agree to disagree...
