Boyle was attacked by certain newspapers and Twitter users after he made jokes during the Paralympics Opening Ceremony on the social networking site. Meanwhile, Channel 4 has reportedly ruled out working with the comic again over the incident.
Fellow stand-up Howard said that he was shocked at the fall-out from the jokes, claiming that he found the critical response to Boyle "strange".
"We live in a democracy and everyone knows what Frankie does. Some people find it hilarious and love him, other people don't. If you don't like him, don't listen to him. If you do, do and enjoy it. I don't know who these people are who are really furious," he said.
"Nothing really offends me because I'm a comic and I've seen and heard far worse stuff. I've seen some full-on things in my time, but at the end of the day, they are all just jokes."
Commenting on the press coverage of Boyle, he added: "They only print the most incendiary jokes, they don't print them all, which isn't fair.
"There are far worse things in the world than the jokes that Frankie Boyle writes. There is a war going on in Syria, so that's probably more important and maybe people should be more focused on that."
Russell Howard's hit series Good News will return to BBC Three later this month.
