A WA Labor MP has told state Parliament more violent people are on the streets because they are not being sent off to war.

During Parliamentary debate about the classification of video games, the Labor member for Forrestfield Andrew Waddell said the people who commit the violence would have in the past been sent off to war.

"The reality is we are not culling the young anymore," he said.

"We are not sending them off to a foreign battlefield to actually kill other people and so consequently that is why they are on our streets.

"That's the reality, we haven't had a major conflict in a very long time."

But the Liberal member for Jandakot Joe Francis who also serves in the Australian Navy says Mr Waddell's comments are offensive.

"I am disgusted and appalled that a member of Parliament would say such a thing," he said.

"If the Labor party had any integrity they would sack this member today."

Mr Francis says Mr Waddell has no regard or respect for anyone who has served in the Australian military.

Mr Waddell holds the seat of Forrestfield by 0.2 per cent.
