If the group you protested with were engaged in terrorist actions then you are. You want to go join a BUAV rally thats fine. And I wouldn't dream of calling you anti science. Nor would I accuse you of being anti science for protesting at a Greenpeace or Friends of the Earth rally. SHAC/ALF are a terror group. Attending a SHAC rally, giving money to SHAC, etc. is funding terrorism.
Protecting the identity of a member of SHAC is supporting terrorism.
Seeing as SHAC is a lawful public group, whose members are well-known to the authorities, I doubt it somehow.
The ALF and the ELF share many members and are populated by people who engage at attacks on scientists. If you support the ELF or ALF you are anti science. I'm not equating attending a Greenpeace or BUAV protest with being a member of the ALF.
Now you are descending into self-parody.
Thanks for doing my job for me by making yourself look like a raving lunatic.
