Red Bull founder Dietrich Mateschitz has told Neue Voralberger Tageszeitung that only "hardcore fans, hooligans and ultras" and thus a "minority" do not want RB Leipzig in the Bundesliga.
Having won promotion to Bundesliga last summer, RB Leipzig have faced strong protests from several fan groups in Germany, with some, like those in Dortmund ahead of February's league match, also turning violent.
RB Leipzig have been strongly criticised for bypassing the 50+1 rule as well as forming a club as a marketing vehicle for a brand, a first in Germany football, and for spending vast amounts of money on their team.
However, Mateschitz believes that only a handful of supporters do not want the club in the Bundesliga.
"We talk about hardcore fans, about hooligans or ultras, who misuse football in general and Red Bull in particular for their propensity towards violence and conflicts," the multi-billionaire said told the Austrian paper on the 30th anniversary of Red Bull's company foundation.
"There is a minority in football fighting a class war, and only wants to be drunk or set off fireworks," he added. "I take note of it, and that's it. It doesn't offend me."
FC Schalke director of sport Christian Heidel and Borussia Dortmund chief executive Hans-Joachim Watzke have also been critical of Leipzig.
"That a few presidents feel like showing sympathy for those things or even agreeing to it, might not be thought through fully, even more so if you look at their own financing," Mateschitz said, in comments that could be interpreted as referring to BVB, the only stock-listed Bundesliga club.
"Sporting success matters in football, as well as fairness towards the opponents and the overwhelming atmosphere in a sold-out stadium. Without a doubt, we have achieved this," Mateschitz said, adding that he believes Red Bull's "real crime is that we not only play football but moreover have success."
"We won promotion four times in six years, and we are now, and we are very proud of it, ranked second in Bundesliga with one of the more low-priced and the youngest team in the league," Mateschitz said. "If you compare a team like Leipzig to Bayern Munich, it is like a battalion full of recruited with Roman mercenaries in their last but one battle."
At the weekend, RB Leipzig made the next step towards automatic qualification for the 2017-18 Champions League season after beating Bayer Leverkusen 1-0. With only six matches left to be played, they have an eight-point lead on fourth-placed Borussia Dortmund.
There have been suggestions in the past that UEFA could deny Leipzig access to the biggest European club competition should RB Salzburg win the Austrian league and thus also enter the Champions League during the qualification rounds.
But speaking to kicker, RB Leipzig executive Oliver Mintzlaff, who reportedly stepped down from his post as Red Bull head of global soccer, said he believes the club have done their "homework" and are acting within the UEFA rules.
"If we qualify for Champions League, we will take part in the licensing process," Mintzlaff said, adding that RB Salzburg and RB Leipzig "are totally independent and free in their decision making."
