In the case of Homosexuality:
1. What consenting adults do in the privacy of their bedroom is their business.
2 The only time it should become my business is if people are being hurt because of it (persecution / assaults.)
3. If you don't want negative opinions of your lifestyle, don't make it other people's business. I'm not saying hide who you are, but public displays because you require validation makes the voicing of different opinions completely valid.
In the case of Free speech:
1. No speech should be censored.
2. There may be consequences that come from using this freedom, and we need to be prepared to accept them, but we should never be told we can't.
Tolerance isn't when others agree with you, it's them accepting your freedom even when they don't.
