You can say whatever you want: you should also expect to take heat from non-like minded people. At some point the free speech concept transitioned to "I should be able to say whatever I want with no consequences". The First Amendment is very specific:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
Says nothing about any one else's responses to your words.
