they've been saying this forever. they're crazy. they also call sri harimandir sahib a shiv ling! and they already think gobind = krishan and ram = ram chandar. they spread lies and some poor uneducated souls are taken in. they support deras and influence sants. they say kes is not necessary or that the keeping of kes came from shiv! they say khalsa is the savior of hindus. they twist sikhi to their own means to try to destroy our spirit and absorb us into their quam. they do this out of fear, fear of our bir ras. fear of our strength. and fear of khalsa raaj.
but they can't harm us, now matter how they try. as long as we follow guru sahib's hukam (ALL of it) and do naam jap, they cannot influence us. and those poor souls who follow them are destined to come back into this world until they find guru sahib's sikhi.
we can do prachar, but to the ignorant, it's just us against them. and since the RSS teaches an easier form of worship, a lower form of worship, they will always capture some lazy souls. it's just not in their karam to become Singhs. that's ok though, we need proper Singhs, not sheep disguised as lions!
just my humble opinion. i believe in quality rather than quantity. those blessed with guru sahib's kirpa will never turn their back on Sikhi!
