Im not proud of it now, but likewise 14 year old me idolised Sid, but even then I was aware that his swastika was for shock value rather than a political position, he was a thug, not very bright, and easily led.
Back then all us punks knew was that the swastika made Grannies clutch their pearls, and didn't really stop to think why, we just did whatever got a rise out of the older generation.
looking back now I cringe at our naivety
