Go on a road trip. Go surfing. The great thing about London Calling is that it is very accessible. It combines punk, pop, and reggae to make a diverse and interesting album.
You have two choices: continue to be the close-minded moron that you are, or expand your horizons. If you were smart, you wouldn't listen to the superficial reactions of people who are completely ignorant of punk as a genre. If you were smart, you would know that it takes multiple listens to fully appreciate an album. This should not be news to a music historian.
