There is still hate out there directed towards guys with beards and it's something we need to work to change. We don't do that by returning hate with hate, but actually by being positive, warm and welcoming.
Those inappropriate beard memes are great to share within the beard community as we all get a kick out of them, but they can be a turn off for those who don't consider themselves a beardsman. When you see a hate train going on for a beard related post - simply post some positive content and show the world that beardsmen are just ordinary guys with facial hair.
Don't engage in their tactics and it's best to take the high road.
