Free speech includes the right to be heard.

That's why the government is allowed to kick you out of political rallies/meetings if you're just there to protest or whatever; you're not allowed to try to shout over someone else to prevent them from talking, rather if you disagree with them then you need to go find your own followers to try to convince.
