"If a Russian politician is not ready for tough rules, then it is better [for him or her] not to start a career," Russian politician Vladimir Zhirinovsky wrote on his Telegram channel.
Commenting on the incident with Ksenia Sobchak, the politician noted that "it's much easier to ask questions as a journalist or host an entertainment show," because there is no one to offend you.
According to Zhirinovsky, the political environment is much harsher, and requires a certain endurance and true grit.
"Politics is not a discussion between friends, but a struggle of opponents, a struggle for power," the politician added.
