Horner has endured a tough start to the current F1 season, especially in the wake of the team orders controversy in Malaysia when his leadership was undermined by Sebastian Vettel.
That resulted in questions being asked as to whether Horner remained the right man to run the team.
But the 39-year-old fought his corner, as with other causes in the recent past such as leading Red Bull out of FOTA (Formula One Teams' Association) and opposing the Resource Restriction Agreement.
On the back of winning three consecutive drivers' and constructors' championships, Horner appreciates his standing in the sport.
"My job is to do the best I can for the team, to protect the team's interest and every employee's interests within the team, as well as the drivers," said Horner, speaking to Autosport.
"At the end of the day, it's not a popularity contest.
"Of course when you have success the quickest way to become unpopular is to have sustained success.
"The success Red Bull has enjoyed over the past few years sits very uncomfortably with certain members in the paddock.
"There are teams that have struggled to win constructors' world championships that have been around for a long, long time, and that inevitably doesn't sit well either.
"My focus is to do the best I can for Red Bull Racing, and if that means you're not the most popular, or you're not invited out for dinners, then I don't care."
Horner further understands in a world dominated by social media just how quickly perceptions can be formed and voiced.
Although Horner believes his running of the team should not have come under the scrutiny it was subjected to, again he has no doubts about his leadership qualities.
"When you've competitive drivers, of course you're going to get issues that sometimes will get turbulent," added Horner.
""But in the modern world, with the way social media exists, opinions are voiced instantaneously and quite often based on zero fact.
"I'm judged on what I achieve, not how popular I am. I think I achieved a lot before I came into Formula 1, and I've achieved a lot in F1.
"I'm judged not on what I say, but what I do. What we have achieved at Red Bull - 36 victories so far, 48 pole positions and six world championships - shows we've joined a very select group of teams.
"You don't do that without there being discipline, without there being organisation and without ticking every single box, especially against the quality of opposition we're competing against."
