Norris caused a stir in last weekend's Dutch Grand Prix when he angrily slammed the team for leaving him out too long on slicks in the rain, shouting "are you stupid" to his race engineer.
When asked about his comments in Monza, Norris admitted he was taken aback at how aggressive he can come across on the radio, while he didn't intend any offence.
"When you look at it after you always think 'I make myself look like an idiot' and I get that," Norris said. "But the people I speak to know that I would never mean something like that, of course.
"I always sound like I'm crying or moaning on the radio, I don't know why. I hate it!"
Team principal Stella said he has no issue with Norris' vocal radio calls and the team prefers being "heavily challenged" by its drivers rather than them being passive.
"He was obviously frustrated because he realised that we were missing an opportunity by staying out one lap too much. And this is because the people misread the situation, so Lando was addressing it," Stella said in Monza.
"This is what champions do. We like this character. We want to be heavily challenged by the driver. And we can be heavily challenged because our culture is strong, we can bear with that.
"We'd rather have this kind of challenge than a passive driver that just takes everything and doesn't contribute to the development of the team. So, for us this episode is not a problem at all."
