Why do people yell and get mad on here ?

I asked a question about a great dane being outside and people got really mad and started ranting ! I'm sure most people should be happy im on here asking then just going out and paying for the dog and throwing it out . I asked a simple question because i was curious and was interested on the dog breed . They called me a brat and a animal abuser !!! I love animals with all my heart and want to be a veterinarian when i grow up . My mom said i could get a kiddie pool and a big fan for the dog outside . It could go in our air conditioned outdoor room . we spend alot of time outdoors and i play with my dog all the time . So why am i a brat and a animal abuser ?
