Should there be limitations on the right to free speech?

No. But that doesn't that mean speech should be free of consequences. Just that you won't get into legal trouble for having an opinion and voicing it. Shouting fire in a crowded theatre when there is no fire means you should still be liable for injuries from an ensuing panic. Sprouting racist or homophobic slurs won't get you jail time but certainly makes you a valid target for public mockery and for people to decide not to do business with you.
