Ok i maybe wrong talking about it like plastic but it is still a human made carbon polymer and i do have concerns about very tiny particles coming loose and ending up somewhere in my body. It may be 100% harmless or it may cause whoever knows what, so where possible i rather avoid using it and stick to proven technologies that have been around longer and are known to be completely safe. It is simply unknown to the body so unless somebody can prove to you that there is no chance it ends up in my body i'd rather use something else for the circumstances that i do not absolutely need silicone. I do not avoid it 100% either. Many of my stainless steel or glass containers have silicone rings to make them airtights.

Definitely thanks for the long clarification.
