This is a bit of stretch. Shiva is the god of destruction and is frequently avatared carrying weapons. While the scriptures may preach compassion, this is not what the majority of adherents see and observe.

There are many scriptures related to shiva, you are just picking one aspect to suit your agenda.

so you know about Noah's arc and sodom and gemorra, right?

And do you? Do you actually understand what and why it happened?

You are grossly misinformed about the history and practice of Hinduism and Saivism. You're repeating stereotypes.

Please cite your sources. Tell this to the South Indian Tamil who say Anbe Sivamayam, Satyame Parasivam (God is immanent love and transcendent reality).

The "Siva as destroyer" is imagery is perpetuated by firstly Hindus who don't worship God as Siva (e.g. Vaishnava, who worship God as Kristna), secondly by the "spiritual but non religious" people of both Hindu heritage and not, and finally by e.g. Christians.

In Saivism there is one aspect of Siva that is "destruction" but it is a synonym for "dissolution" and is not a scary aspect.
